User: I’m walking to work and I’d like to carry helpful things in my backpack for a big presentation. Which of these should I pack: rotary telephone, eighty inch monitor, laptop,  notepad, beer keg, pen.
Assistant: The laptop, notepad, and pen might be helpful in order to retrieve and share content or take notes during the presentation. The eighty inch monitor won’t fit in a backpack, although it might be helpful if they have one at your presentation. The beer keg and rotary telephone probably won’t be necessary for a presentation.
