person A: I didnt think to invite my sister to a party I recently helped put on.
person B: Uh oh. I bet she wasn't happy when she found out.
person A: No she wasnt. In all fairness it was a group of people I never would have thought she would have wanted to hang out with.
person B: Yeah_comma_ I can understand that.... But it probably would have been best to invite her anyway_comma_ just in case.
person A: you are right. Guess I know better for next time.
