I keep reading posts where some people think this guy was drunk or that he was not careful enough and thus lost his phone. The only thing I have that I truly take care of and try not to lose is my wallet. I seriously try to be as subconciously aware of it as often as I can. Nevertheless, I have lost 2 wallets in the past few years and I have been sober both times. It happens. The first was while on a CTA bus in Chicago and the second was in a Taco stand. Both times I thought I had put my wallet in my pocket but am pretty sure it fell out since I tend to carry too much stuff in my pockets(pens, change, iPod, flash drive, headphones, phone, etc...) So yeah, it's plausible to lose very important items regardless of how drunk or sober you are. We are only human.
