I left my iPad on a plane the other day. The crazy thing about it — as if there needs to be an extra layer of crazy about leaving a hugely expensive and personal and professionally vital device on an airplane — was that I thought about it five minutes before I did it. Not after. BEFORE.
[So, ok, I haven't (yet?) left my phone somewhere or iPad or whatever… but I do know that feeling and I try to pay attention to it. When I put down my keys and something whispers in my ear "You'll not remember where you left these…" I try and not just chuckle, but pick up my keys and not put them there. Or tools while I'm working. Or whatever. And yet with all that, having just come home from a vacation, I couldn't find my keys this morning nor several other things that are usually in one pocket of the bag that I usually carry. It would have been easier to take the bag along without removing anything… next time. BTW, Have you seen my keys?]
