I did once. He said something to the effect that he thought I was a really good person, then followed it by saying, "if I didn't, I wouldn't not be nice, but I couldn't say that I think you're a really good person as easily as I do." It was something like that...lol.
He was nice. That was the only time that I asked him. He pretty well lets me know on a regular basis that he things I'm a good person, if messed up.
It made me feel good to ask...well, his response did.
GL!
