Thanks. I read up on it and found out that people can use the info to take money out of your account. My mother had told me to give him the info, but I wanted to check first and decided not to. She later told me she would have been mad at me if I'd given the info out (even though she told me to do it). I think I'm going to see if he can pay via checks or something. I've heard that Paypal charges the recipient of the money a percentage. Since it is repayment of a loan, any costs should go to the person repaying, not to the person receiving, but I don't think Paypal works that way. I've heard Facebook has a thing where people can receive payments, but I don't trust Facebook anymore for that sort of thing.
The situation is further complicated because the guy's girlfriend had another incident of diabetic ketoacidosis. He got home from Texas and found her cold and unresponsive. Her temp had dropped to 90 degrees and her blood sugar was 800. On top of that, she now has pneumonia and is still in the hospital. I believe she was watching his two children as well as her own and now he has to watch all 4 of them.
