I answered a ad on Craigslist to care for a ladies cat, she is in between houses, we went to pick her up because she has no car, so I felt bad, she provided food,litter,cat treats and stuff, and asked me how much does she owe me, I felt bad to even take money but she said ok heres 10 and you decide what to do with the 10, its between you and God, buy a homeless food or buy little kids ice cream?? She comes once a week to visit the cat, how much is reasonable? My husband keeps telling me I need to ask her for money, Please advice??
