Input: Text: after reading that title, i bet you're thinking 'that's not so bad, you probably just hurt your hand.' guess again. by the way, this was about 6-9 months ago.

okay, so i was pretty pissed off at school. i was having a... colourful rant. now picture this corridor: you walk in, and to the left is an english corridor, in front of you there is a hall, and to the left there is an i.t corridor. i'm standing outside my i.t classroom, off the back of a d in my physics test. not a great start for the day. my friends particularly like it when i rant, so they are effectively standing there, pissing themselves with laughter. 

in a rage, i throw a punch in the air, and spin round, as you do. i'm fully intending to punch the air. however, i completely screw up this ragey-air-punch, and punch the wall. only to find it is a makeshift wooden wall which has been painted over. the wall breaks, much to my amazement (i'm not exactly the strongest kid, so it must've been a pretty weak wall) and it collapses straight onto around 4 computers, knocking them off their stands, breaking them. this is the moment my principal walks round the corner, to find a broken wall, 4 broken computers and me wailing at my very sore hand. as if it couldn't get any worse, one my friends genuinely pisses themselves with laughter. he doesn't realise until everyone looks at him in disgust, hears various loud 'eurgh!'s and a wet patch beneath where he was stood.

it gets even worse, but expectedly worse, as i have to pay for all the damage and get one hour after-school detentions for a week. a truly incredible, unintended fuck up.
