I went through summer camp and youth group with a minor child actor who became a fairly well-known celebrity (we'll just call him Sam, which is not his name). Sam was in and out of school as a kid because of his career, and he was teased a lot for this. He usually didn't work during the summer so he could have a few weeks to be normal, and youth group was mostly the same people as from there. His acting rarely came up in conversation, mostly because he was too much fun in person to be bothered about anything else.
The only time there was ever a problem was, as Sam became more famous, that I didn't think about adding his email to a mass email (NOT a forward, just letting people know I was moving). Honestly, I had forgotten that he was a celebrity! He forgave me and changed his email address, but that was the moment that I realized how much he valued the separation of his personal and public faces.
