Input: Text: so today i fucked up reddit. after a long day at work i was rather excited to go on a night out, as i hadn't been in a while plus a friend i hadn't seen in a while came down to visit. due to this excitement i forgot that i had run out of hairspray and thus neglected to buy new stuff.

after showering i realised my grave mistake however life is not without a solution, and i decided to wear a snap back. after meeting my friends they decided to try and knock the cap off as much as they could, all a joke of course. anyway we went outside to smoke and came back in, but just before we got to his door he threw my hat away. in my slightly inebriated state i run to grab it, then charged the door to stop them locking me out.

well apparently i decided to try and juggernaut it and break it down, but hit it wrong and knocked my front tooth half out exposing a nerve. after realising what happened, and seeing half my tooth out i decided to call it quits and see what i could do to stop the pain. unfortunately i had to wait until morning as dentists tend not to be open at night. 

waking up this morning and the reality struck as the alcohol, 8 pain killers, and adrenaline had worn off. who would have guessed an exposed nerve would hurt??
