Haha was it that obvious?
Edit: I've got a good story about the "person walking behind" grievance.
A good mate at uni (let's call him Warrick) was telling me that one day in high school, he was walking home and there was a kid behind him who had kind of caught up to him. Now this kid, for some reason, didn't want to overtake my mate. I think he thought he might get picked on or something. I don't know why because my mate isn't that type at all.
Anyway so Warrick was kind of getting annoyed and every time he looked behind, the guy would look away up at the trees and pretend nothing was wrong.
Warrick decides to start slowing down to see if the kid would walk past him. Each time he slows down, the kid slows down too. It gets to the point where my mate just stops on the footpath and waits, but nobody walks past.
So he turns around with a pissed off face and the kid is just standing there, hands in pockets, looking around at the trees as if there's a cool bird that he has noticed.
Warrick goes "What's going on mate?" and the kid just responds "What? nothing".
So my mate just walks off and the kid starts walking again. When Warrick turns into his house, he hides and watches the kid go past, who starts running home once he got past the house.
True story. Funny as hell.
