I started online when I was 13, but back then there were local BBSes - does anyone remember them? So not only was I meeting all these cool people online, but they were all in my city, too. There was an even mix of teens and adults, and we even hung out on Thursdays, I think, and met all of each other in person. I remember walking down to Starbucks to meet some guy I met on a BBS. How naive and lucky I was!
My fiance's nieces are 12 and 9, I think, and I don't know if they have a FB. Their dad does, but he's never on. I keep wondering if I should have the internet safety conversation with them - I've given it to a lot of parents over the years. I'd search for and friend them myself, but I'm not really appropriate for the under 18 crowd. Maybe I will search them out - that will at least tell me if they have a public page or a private page - small things like that make a huge difference.
Oh, and that waddling to the phone thing - I don't use the phone, it's part of my PTSD. So I keep in touch with all my friends through facebook - I like to hear how their day is going and I have people I trust that I can ask for 'sanity checks' and the like.
