This past Mother's Day, I (M, 34)was the only person available on the actual date of Mother's Day as my older and younger brothers(36 and 28) were going to be doing stuff with their families, and then we would do something with the entire family the following Thursday. So on Sunday my dad, my mom and I went to a local Mexican restaurant, and I took care of the bill which came out to $54. Then on Thursday we went to my mom's favorite restaurant. I was one of the first to arrive and I sat down with the mindset of trying to sit next to my younger brother so we could talk, but I was told to by my mom to sit on the other side of the table so that my brothers and their families could sit together which resulted and me sitting next to my 2 nephews. After dinner, my younger brother called from across the table(first time he spoke to me the entire night), and said "How do you want to split it?" Here's where I might be the asshole: When he said that the first thing I said was "I already took mom out on Sunday." He just kind of stared at me, confused, so I repeated, "I already took mom out Sunday and paid $54." He just continued to stare at me, and I didn't say anything back. Then I went to the restaurant while he took care of the bill on the tablet thing. Here's the thing, if I was told beforehand that we were going to split the bill I would've been fine with it, but to tell me when the check comes and it be the first and only thing you say to me the entire night rubbed me the wrong way. So, am I the asshole? EDIT: At restaurant the waiter asked my father if it was going to be one check or separate. I waited to see what he said, but he said one check. So I wasn't expecting to pay anything.
