Yes I agree but I still wonder if I should give him more time to see if he gets further out of his shell (he started after all) ? Or should I just tell him to stop behaving like that (may be risky) or just ignore him more in the hope it will make him think. I don't meet him much by chance so I can't just leave things to chance.
Yes, he is a sweet person with his daughter and father. He has about 10 pictures of her in his office.
