lately, money had gone missing from various peoples houses and the only real similarity was that my friend, lets call him lucas, had been going around each of them. he was leaving for denmark soon and he decided to have a massive farewell party. as things had been pretty rocky before he left between us, we decided to just even things out when he came over. we had fun, played league- all around a good time until he left when my maid found out that 100$ had gone missing. of course i called him up and he denied it even though it was obvious as we had security systems installed in our kitchen. 

anyway, the next day was suppose to be his farewell party, and we were all invited. because i was spiteful to him stealing from me, i decided that i wasn't going, but i also didnt want anyone else to go. so i pulled a dick move and got everyone to not come because of what he did and while doing so i told him to buy a lot of booze since we were coming. 

a few hours before we were supposed to show up, he snapchatted all of us a picture of all the booze, easily 600$ in stuff not including the snacks and mixes he bought. 

i felt guilty but a part of me justified it as he had stolen from us all. so come a couple of hours and he messages all of us wondering where we are and doesnt get a reply. the next day he leaves and non of us have spoken to him since.

i fucked up because even though he stole from my friends and i, i still dont think it was very nice having nobody show up to your farewell party and its been bothering me for a while so it feels good to come clean.

TIFU by trusting my best friend
