I don't know if this the right flair but anyway. I have been seeing a guy for 2 months now and so far everything is going well. But last weekend we went for dinner at his sister's home and she's great and adores her brother. But something that bothered me is that he didn't bring her anything not even wine or dessert and after dinner I offered to help her with the cleaning but he didn't. And it's been bothering me. I think it's basic manners to offer help as a guest after dinner and bring them something. What do you guys think? Also English isn't my first language, sorry for any grammatical mistakes.
