[EX Q]: Pauline Hilborn   a mom of two in New York City  describes  herself  as an expert on meltdowns based on the experiences of  her  daughter  who  she  says is "7-years-old but sounds more like 13."
Case in point:  Hilborn's daughter  wanted a ponytail like the pop singer Ariana Grande  but felt like  her  mom didn't do the ponytail properly and put it in the wrong place.
" She  came out crying and said  'Ariana Grande's ponytail is here not here '" said  Hilborn   pointing to the place on  her  head where  her  daughter preferred the ponytail to go  not where it ended up.
 Pauline Hilborn  and  her  kids  ages 4 and 7.
"I was at a loss for words "  she  said. "I had no idea what to say but my husband said  'Well   she 's right you know ' which didn't help the situation."
Debi  another mother of two in Manhattan  says her 7-year-old has definitely had some tantrums. When I asked  her  son what a meltdown is  he told me it's when you cry a lot. When I asked him to imitate one  he said he keeps screaming until his mom lets him have whatever it is that he wants at that moment.

[EX Q]: Sen. Elizabeth Warren  D-Mass.  said Thursday that the Democratic primary last year was "fair " moving away from the comments she made last week.
"I agree with what Donna Brazile has said over the last few days; that while there was some bias at the DNC  the overall 2016 primary process was fair and Hillary [Clinton] made history  " Warren  said in an interview with MassLive.
Last week  when asked by CNN's Jake Tapper if the Democratic National Committee had been "rigged" to favor Clinton   Warren  answered  "yes."

"We've got to hold this party accountable " she continued. "When Tom Perez was elected to chair of the DNC  the very first conversation I had with him was to say  'You've got to put together a Democratic Party in which everybody can have confidence that the party is working for Democrats rather than Democrats working for the party.' "
A spokeswoman for  Warren  later told MassLive that  Warren  believes  as  she  said last week  that the DNC was rigged  but that the primary itself was not.

[EX Q]: North Korea is opening the door to possible talks with the United States. The message came from a North Korean delegate at the Winter Olympics during an hour-long meeting with South Korea's president yesterday. North Korea and the U.S. haven't held diplomatic talks since 2012. So could that stalemate break?  NPR's Elise Hu  is in Seoul and joins us now. Hey  Elise.
 ELISE HU   BYLINE: Hey there.
 HU : This certainly is the first time that North Korea has signaled a willingness to talk with the United States in years  but talks themselves are unlikely anytime soon because this is so vague right now. The South Korean presidential Blue House put out a statement yesterday that North Korea expressed a desire for talks that was again confirmed today. And North Korea agreed that as these North-South ties improve that there should be an improvement in North Korea-U.S. ties as well. And this is really helpful to the South Korean president  Moon  who really hasn't wanted to look like he's not getting anything from the North in return for all of the peace and goodwill gestures he's offered during the Olympics. So one of the demands by South Korea seems to be that the North be more willing to reopen dialogue with the U.S.
MARTIN: All right. NPR's Elise Hu for us this morning - thanks so much  Elise.
