And I'm kind of serious about this. My mom is useless when it comes to modern technology.My parents would never understand how to text. Or even use a smartphone without causing a nuclear explosion somewhere.
I mean. My mom barely knows how to use a DVD player (she's better at the VCR, not much better though). She knows how to turn on the TV, but don't ask her to change channels. She'll get confused.
My dad... can figure it out. He just starts out confused and eventually forces his way around. At least, give him time and he'll understand how to do stuff.
