I'm 18 and some of my closest friends I met over the interwebs.
>>1 The idea of meeting a friend for the first time or even using your voice to communicate with them can be scary especially if you're younger than them. I personally never advise talking to people you haven't known for awhile, and never disclose any personal info. Now as for the voice. If they're your friends, youll get picked on in a playful manner but they will likely not treat you any different if you act their age.
