This couple that was in the same train as me, left their seats to change the diaper of their little baby.
Not only did they go away from their luggage, but they left two phones and a large tablet visible and unattended for quite some time!
What're you, casing the joint or somethin'?
Jason Bourne over here identifying everything in your bag every time you turn your back just in case he needs to call someone in the government and antagonize them for a few minutes.
What's your next move - take the strap off the bag and use it to tie yourself to the bottom of the train so a bald guy can't find you?
Seriously, though, you should steal that shit.
