Input: Text: hello reddit this is my first post so go easy on me. i've been laughing at tifu's for a long time now and yesterday was the day i fucked up too.

backstory: so my dad is one of those badass dads that likes to smoke, chops wood and of course uses chainsaws on a daily basis. he's trying to teach me a thing or two sometimes so yesterday i went with him to help him chop down a tree and cut it into small pieces so we can use it for our fireplace.

we bring the tree down and he is cutting the smaller branches with a big  as fuck chainsaw while im cutting them with a smaller chainsaw which i can easily hold with one hand while im holding the tree with my other hand, while im cutting a rather small branch something happens with my chainsaw and it kinda jumped a little and it landed on my left thumb. i put the chainsaw down, tell my dad and we go inside our house, he pours some whiskey on top of it and bandages me. we light up a smoke and laugh at my dumbness and how i almost lost a finger.
