Text: title speaks for itself really... 
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

New input: Text: so it started as a normal depressing summer day where i have no friends and nothing to do so i sept all day. well eventually my mom got her form of concerned with a little pissed mixed in and told me to do something, so naturally i call my bro and set up a bro date as my girlfriend likes to call it. so we're going to a classic rock concert on friday so we went to buy zippo lighters yesterday but forgot to buy lighter fluid. so we go to walmart today to get that lighter fluid and ended up walking out of there with 2 bb guns along with the lighter fluid we were looking for... idk how we talked ourselves into it, but we did. so anyways were outside my house in his car opening the bb guns and we had to break zip ties. well my idiot of a friend decides instead of scissors let's use his pocket knife. it goes just about as well as you think it would and i slice my hand open. so i'm sitting there like "shit" as blood streams down my arm. my friend says "lets go inside and get me cleaned up" and i'm like "hell no" cause if my mom found out i bought a bb gun she'd kill me after making several you'll shoot your eye out jokes. so he's just like "well what do you think we should do", so i tell him to drive to walmart, we'll buy a first aid kit and clean me up in the bathroom. he's like "you have blood down your arms" and i'm like "no one will notice if we don't make a scene now drive!" so we get there and the first thing that happens is we see our friend's mom and she, being a mom stops and is all like "oh hi!" and goes in to hug us. well i'm sitting here like "shit" cause i don't wanna stain her shirt so when she hugs me i keep my hand off of her shirt to keep it from staining. so then i run into the bathroom, my friend buys the first aid kit and we patch me up.
