i just wasted $1500 of my parents' money.
i feel terrible.

edit: i guess it wasn't that i took the wrong class, but the class i was taking wouldn't transfer credits over to my university. so really it was my negligence to do more research in the matter. gg

Text: i was sick and was dragged to the super market with my brother, not really concentrating he told me to go grab laundry detergent. i go there and spend 10 minutes in the aisle looking for the damn thing with no success.

 i get tired grab my cart and go looking for him. it's a huge super market and not usually the one i go to, so i'm not familiar with the layout. i spend another 20 minutes looking for him in vain. the cart is really heavy so i decide to leave it in close to a landmark and fetch it later. i look down and i think to myself "why is he buying that, we have no need for this... we don't have need for any of this" that's when i realize i have been dragging someone's shopping cart around the super market for the last 20 minutes and someone must be insane after this thing. 

i ditched it, sat in a corner until my brother passed by and went to hide in the car until he was done. sorry stranger! it was an accident!
Answer:
TIFU by accidentally pranking someone
