I think this really applies to all the high schoolers and college students here. As for telling people, I'm a lot like SLC1. I don't really care about telling people about it, but I don't go out of my way to tell people about my hobby. Most of my close friends know about it, and a few have even gone out to EWR
with me. I am very wary of going on a.net at school, though. As for family, no one in my family likes or even knows anything about aviation, and they really don't understand it. They really don't care, though, and let me do my thing, as long as it doesn't interfere with school.
