The fact that you tell this story shows that you eventually did get the hint. A lot of times, I've had the experience where someone says something and it goes right over my head, but when I'm reviewing and analyzing the conversation later (because I always do), I realize they were hinting at something and I missed it in the moment. One time in high school, I was playing with a new phonetic alphabet and someone asked what I was doing. I told them and showed them how it makes spelling words so much easier. They said, "Oh, how do you spell 'antisocial'?" Naturally, I showed them, and then went on with my practice. Days later I was thinking, "That was a weird word to pick. I wonder why....ohhhhhh!"
I can't tell you how many times my colleagues have interrupted a story of mine and said, "Get to the point!" So now I offer as short a summary as possible and then see if anyone asks for more details. They almost never do.
