Dear Queenie,
When my sister was coming to visit me she let me know when and how long she could stay and she asked me if there was anything she could bring. I said she could bring some food that we all like and told her how many people would be there. She said it was up to the host to provide food for their guests.
Queenie, I always bring something to eat when I go to visit them. Was I wrong to ask her to do the same for me?—Offended brother
Dear Brother,
It is up to the host to provide food for his/her guests. The fact that you always bring something to eat does not mean they have to do the same for you, although it would be good of them to do so. And your sister should not have made the offer if she was not willing to do as you asked.
You owe each other an apology, and please do not let this incident become a cause of family estrangement.
