Ok, story time. My FI has been giving me a really hard time over this, so I want to know if I'm a complete freak for doing what I did today.Basically, I got an e-mail saying that I was owed a $2500 refund from my university, through this third party company. I know the place is legit, because it's all over my school's website and everything, but I was confused because I didn't know how I could possibly be owed a refund - I haven't paid my school more than $400 total, because I'm a grad student and my tuition is paid for.I went to our student accounting website and it said that this company handles refunds for people who have student loans and overpay, or something. I don't have a loan, so I was even more confused. I considered just filling out the forms, getting the money, and depositing it in my savings account since I could REALLY use the money for our wedding, and I figured if it was a mistake I could just give it back and maybe it would have even collected a little interest. But I had this guilty nagging feeling, and I just had to figure out why I was getting this money. Plus I didn't want to get too excited about it since I knew I was probably going to have to give it back - but if for some reason it really WAS mine, I would like to know that instead of being paranoid, waiting for someone to contact me about it. So I e-mailed student accounting and asked them if they knew anything about it. Five minutes later I get an e-mail from the third party place saying the refund was taken back, and maybe half an hour later I get an e-mail from student accounting saying it was a mistake, the money was supposed to be sent to my department for overpaying my tuition - not to me personally. I was really bummed, but didn't think much of it, except that it was kind of emotionally draining and I had to go through a lot of crap to set up an account with these people...But I got home and my FI won't stop telling me he can't believe I didn't just keep it without saying anything. He says it's not my job to look into other people's mistakes, and that I could have at least collected interest for my troubles. Now I feel like an idiot, and kind of like I have a freakish sense of guilt/paranoia for trying to get it straightened out rather than keeping it. I can't explain why, it's not like I thought I'd get in trouble, I just couldn't handle it. Am I weird? What would you have done???
