When you’re late for the bus it can be very frustrating. Particularly if the bus the pulls away just as you get to the doors and you try to look all casual, as though that was meant to happen.
But what you shouldn’t do is argue with the bus driver (he’s never going to open the doors for you if you are like that) and you shouldn’t chase it down the street with your trousers round your arse.
This guy learned both those lessons to his cost as he faceplants when his jeans get a little bit too low and send him flying.
His next birthday present should be a belt.
