On being old and out of touch

Now that Offspring is turning 13 in the relatively near future, I asked if he wanted to get a facebook account in after his birthday later this year. He shrugged and said maybe, but that it was mostly for old people (LOL). He said that what he really wanted was instagram and snapflash - or flashchat - or snapchat or some such thing. I had absolutely NO idea what it was he was talking about. I honestly had to look it up on wikipedia. I am officially old!
