So, a many years ago I went out a couple of times with this guy. It seemed like we hit it off pretty good. We go out like 3 times the first week. Then about the 4th date we went to a party on a Saturday night at some of his friend's house. They were discussing nuclear fission, except they were calling it fusion and vice versa. So, I entered the conversation and explained the difference.
The guy looked at me and said, "Wow, you have a brain."
He never asked me out again.
But, we did remain good friends for years. :-D He was best man when I married Myranda's dad.
Did that in high school quite often.
