Answer 2

Gee Patrick, I was messin' with computers 13 years before you were born. I'm 39 years older than you... We old geezers invented computers and video games and cell phones and all the cool modern devices that your generation enjoys. OK, to be honest, most people my age don't know squat about computers, and I spend WAY too much time fixing their computers. But anyway, we know about all the stuff y'all do or are into. Many of us are in denial about it (mostly parents) but trust me, we've been there and done that.
