DH's grandmother has severe Alzheimer's and lives with his aunt. She doesn't know that we got married and wouldn't remember, but she's able to read and knit and do little activities.
Aunt has control over grandmas bank account, so she generously gave us a check from both her and grandmas account in the same card.
Should I send a thank you note to each woman? Or just to Aunt? Grandma probably doesn't know about the money (or wouldn't remember if she DID give it..).. I just don't know what I should do.
