Alona's persistent knocking at the door of room 412 went unanswered for three minutes as she nervously shuffled her feet. Her book bag was super-saturated with textbooks, notebooks, schedules, rough drafts, and various other forms of academic paraphernalia. It was getting heavier. She continued to knock, even though there had as yet been no answer, because the note card tacked to the right of the door indicated that these indeed were Prof. Turgy K. Sigger's office hours. She could see the light under the door and thought she had heard a groan. Just before she decided to give up, slow feet approached from the opposite side, then silence; with a dramatic turn of the knob, the door swung open.
"Was this trip really necessary?" asked Prof. Sigger, blinking and brushing his oily, graying hair back into place.
"These are your office hours," Alona replied. She nervously smiled, feeling the corners of her mouth twitch. Somewhere in the darkened hall, a janitor coughed.
"All right," conceded Prof. Sigger. "Come in."
The carpet was smothered by leaning towers of textbooks. Papers lined the left side of the desk, above which was a small note card which read "To Be Graded." On the right side, the oak finish gleamed of the mid-morning light piercing the Venetian blinds.
"You've come about your final project," Prof. Sigger stated.
"It's only mid-term," Alona reminded him.
"Oh yes, yes," continued Prof. Sigger, without conscious embarrassment. "Mid-term grade. I think I have it here. Somewhere." His hands disappeared into the left side of his desk.
"You told the class that we would get a C if we maintained that Coca-Cola isn't a crypto-fascist conspiracy."
"Oh yes," said Prof. Sigger. "We were discussing social issues, as I remember. I was quoting Marx and some little idiot brought up Rush Limbaugh."
"That was me," Alona muttered.
answer:
Who quoted Marx in class?

question:
Once again, I've analysed my year of travel to see if I'm any closer to reducing it year on year. It's an annual habit, and if often kicks off new ideas that might affect my team's next year of work. The good answer is: yes, there is less travel! And not just that, but having reduced the schlepping I do, I've been able to hire more amazing people to lead on our work, and celebrate one of NoTosh's best years ever in terms of the quality, quantity and breadth of work we're doing.
Key to traveling less has been a marked increase in the number of folk who see and are now reaping the value of working with us online. I've avoided as many as 20,000 miles of travel thanks to greener clients, who are also many dollars better off having not paid for the airmiles that are wrapped up in our regular fee structure.
The quality of our work is better, too, thanks to this. We are doing fewer of those day-long workshops with teachers or leaders, when an hour or even thirty minutes before the day gets started is more worthwhile. We're seeing more school leaders take this up, although it's harder to get teachers into the habit of taking 30 minutes 'me time' to jump into a coaching session on the day or week ahead. But it's starting, and the value to us all is huge. Coaching is very different to 'consulting a Personal Learning Network' on Twitter. It's intense, targeted, focussed and involves a one-on-one discussion that arrives quickly at resolutions to current day challenges that will have a long-term impact. And we come back to measure whether that impact actually happened. I don't think it's a way of working that many are used to in Education, although many corporate clients have had some rare experience with it. Encouraging both groups to take more regular time out for coaching, little and often, is a real challenge, but we're beginning to see some huge impact from relatively little input (and relatively few dollars!).
answer:
Who coaches online?

question:
SEOUL North Korea's sudden threat to pull out of the upcoming summit with the U.S. raises new doubts of whether a denuclearization deal is possible.
North Korean leader Kim Jong Un agreed to meet with U.S President Donald Trump in Singapore on June 12 to work out an agreement to end the North's nuclear program in exchange for security guarantees and an end to punishing international sanctions.
But on Wednesday North Korea's Vice Foreign Minister Kim Kye Kwan released a statement through the state-run KCNA news agency that criticized "unbridled remarks" made specifically by the U.S. president's National Security Adviser John Bolton demanding that Pyongyang completely decommission its entire nuclear arsenal, along with its ballistic missile program and chemical weapons stockpile, before receiving any compensation or concessions.
He expressed "indignation" at the U.S uncompromising position and said North Korea might pull out of the Trump-Kim summit, unless the Trump administration acts with "sincerity" to improve relations through dialogue.
"If the United States is trying to drive us into a corner to force our unilateral nuclear abandonment, we will no longer be interested in such dialogue and cannot but reconsider our proceeding to the North Korea-U.S. summit," the statement said.
The vice foreign minister also said it was "absolutely absurd" that Bolton would compare Libya's experience dismantling its relatively rudimentary nuclear program as a model for dealing with the North's more advanced and expansive capabilities.
He also denounced the Trump administration for "miscalculating the magnanimity" of Kim Jong Un's decision to suspend further nuclear and missile tests, and his willingness to engage in nuclear talks, as "signs of weakness," that were the result of what the U.S. administration has dubbed its "maximum pressure" campaign that led international efforts to impose punishing sanctions banning 90% of North Korean trade.
The vice minister's remarks came shortly after the North abruptly canceled inter-Korean talks planned for Wednesday, citing ongoing joint military drills between South Korea and the U.S.
Last week American and South Korea forces began their two-week Max Thunder exercise that involves 100 aircraft, including eight F-22 radar-evading jets, as well as F-15 and F-16 fighter jets. The North derided the drills as a rehearsal for invasion that undermines improving inter-Korean ties.

Who expressed indignation?
