...I'm sorry. It's not because of Daniel's news, is it?
Sir, I know that sometimes my manners are not the most polished, and I have probably not given the best of impressions in the past. But I do genuinely admire your daughter, and I do not wish to disrespect her in any way. If I pursue her...it with be with the intention of a serious, long-term relationship in mind.
I haven't said any of this to her, I don't feel we know each other well enough to put that sort of expectation on her at this point. I just would not feel right to proceed if I knew that you disapproved.
