I'm the opposite, I can't fall asleep on anything that has wheels :C sometimes I'm tired as hell but i just can't...
But yeah... it's kind of awkward when someone falls asleep by your side at the bus... I try not to move and I wake them up when I'm near my destination in case they overslept and missed theirs
I love sleeping on buses, they're so boring and always awkward, even if everyone manages to stay awake.
I'm pretty fortunate in that the only bus I have to get only has 2 stops and the journey takes almost 2 hours. My stop is the last stop so I can get on and sleep the whole way and not worry about missing my stop.

HAHAHA! I do the sad thing too!
Sometimes, when my roommate isn't home and I'm left with the cleaning, I like to put on really fuzzy socks and just drag my feet across the floor instead of sweeping/mopping.
Hahahaha! At least now I know I'm not alone in the sad looking out of the window thing! I'm always afraid people will see me doing it one day. I even do it in taxis.
Hahaha! I wrap a towel around my slippers and shuffle around the floor to clean up.
