Several years ago I loaned my brother a substantial amount of money. The agreement was that he would take some time to get back on his feet (a couple of years even!) and then pay me back month by month interest free. Well, the time to pay came and went. We had a couple of conversations about it and about 4 years after the initial loan he began to make very small monthly payments. He kept up with these for about a year and a half then abruptly stopped. I let it go for a while, then found out that he was selling some land he owned and making a tidy profit. I emailed him a congratulations note and suggested it was a good time to clear things up. A couple of days later I got a fed ex containing a cashiers check. no note or anything. I sent a note of thanks and general family chat, but nothing back. He is due to come to my house for Christmas along with all the rest of the family. I just feel so weird about this.
