I think it's a tricky thing even with close friends. We've seen it: sometimes we thought we were safe talking with a close friend about something about the kids (trying to play it down, trying to be modest), and suddenly we detect defensiveness and we quickly change the direction of conversation to focus on her/his kid.
Some of my friends love music and they invite us to their family concerts where the kids play for guests. My husband always wanted to be able to have such a concert for our kids. I always object because there is a danger that some friends won't be friends anymore after the concert.
But I'm all supportive if my kids want to demonstrate their talent in front of their friends, at school, etc.
