You take five windows, and a plastic chair, (and a very pissed off feeling)
You smash the first five (Thankfully reinforced glass)
Nice little smashy patterns. going 1 and 2 and 3 and 4 and 5.
Then you realise the first two windows don't feel smashed enough, so you go back and give them another whack to enhance them.
It wasn't me, I didn't do it!
