Is it normal to want to knock down drinks cans/bottles that you see in public.?
... that are clearly not going to be drunk out of any time soon?
If I see a drinks can sitting on a fence/electrics box/one of those little stone things that I think tells you where a fire hydrant is, I have to knock it down with my hand a bit like how those 2p machines on seaside piers work. I then like watching the liquid pour away.
I find it very satisfying to do. I try not to do it when other people are likely to see, but sometimes I can't stop myself.
I like kicking drinks cans/bottles over that have been left lying on the floor and watching the liquid puddle out as well.
