I don't think that I've met such a well-mannered young gentleman until Mr. T came to visit for pics. I would ask him to move for a pose and he'd say "yes, ma'am". As a mother, I was well-impressed. It's really rare to see that in today's time. I hope that all of the hounding of my kids to say yes ma'am and yes sir will pay off one day so that I can be proud when they are around other adults.
Congratulations on your upcoming graduation!
