"well... because he has made comments about it so much to me"

You mentioned a couple of times. Doesn't seem like alot to me. And again it's him thinking out loud. Why do you have to reply?

"and I have suddenly came to this conclusion."

Your conclusion.

"I didn't know how to reply each time he did... any suggestion for the next time he does?"

Why do you always think you have to have a reply? Just let it go.

"He even made the same comment to our D22!"

So what?
