I was out of work for over a week with my very sick son. My paycheck is what goes to pay the sitter for his child care. I was talking to my MIL about how I didn't know how I was going to pay the sitter because I didn't get a paycheck and my dh's had already gone to pay bills. We have a very very tight, strict budge and we never stray from it because we have it there for a reason. I asked my MIL if she thought it would be rude to ask my sitter if I could maybe pay her with my next paycheck. She keeps a couple of other children, and the money is "extra" because her husband has a really nice job. My MIL said not to worry about it, she had no plans for the week and would love to keep my son. My dh was there, too, and she told him we could just save this week's paycheck, put it towards Christmas, and then go back to the sitter next week. We thought it would be a good idea, so we thanked her and told her we'd see her Monday.
Friday I go to pick him up, and she was a little frantic. Said she really needed to start baking for her dinner party that evening. I asked if I could do anything, and she asked me to go to the store and buy 3 bottles of wine. She told me the kind, and so I just asked, okay, how do you want to pay for it? She said, well, I thought that could just be my payment for watching D all week. I explained that I get paid Monday and that I had $5 left after going grocery shopping the night before. I joked I could buy her a cheap bottle of wine, but I just didn't have the money. She got upset and asked how I could not have it when we didn't have to pay the sitter. I told her again that we went grocery shopping, and put some aside in the Christmas fund (though not much) and I didn't even have the checkbook for that account. She told me I needed to call DH then because it was really rude to not even offer to buy it for her. I left a little shocked and called my dh to ask, and he said yes, it was a little rude to not even offer to buy the wine. He would have bought it. We don't buy ourselves alcohol because right now it isn't in the budget. It isn't that I didn't want to buy it for her, but I literally had $5 to my name. Had she not told us she'd watch my son for free, I would have had some cash with me or something.
Should I have offered and not assumed she would actually watch him for free?
