So,...this is NUTS. Completely by accident...I was NOT trying to find this...I saw a link for a crowdfunding page to raise money for his sick daughter. I donated $25 to a friend of mine's crowdfunding campaign, and when I got to the confirmation page there were a whole bunch of other campaigns listed from dog rescues to creative projects and one that said "Help (daughter's name) fight leukemia". I knew it was his kid right away and when I clicked on it I was right--it said his first name and a whole bunch of identifying information confirming it was him and it was a campaign that gave EVERY STINKING DETAIL about his daughter's horrific illness and explained how he and his wife were spending every night sleeping in the hospital and how much they appreciated everyone's help raising money to try to help pay the hospital bills. I feel SO FRIGGING BAD for him. I wish I could give money to the campaign but even if I give anonymously I'm afraid it'll somehow be linked to my name and he'll find out. Oy.

Thanks so much for everyone's advice. I DID send him a request for a bill and I think that next session I will be able to let him know how concerned I am about his situation.

Sheesh. I finally found someone who's really helping me and what a strange and sad complication!
