Parents who won't listen to their (adult) children

[RealUnimportant]

Older != wiser. Back in high school, not long after the home computer became a thing, I admit to being a smartass because I picked up how to use them very quickly. My CompSci teacher was a mathematician by training, and knew nothing about them. One day I was practically threatened with keelhauling because one of the machines failed to respond and it must be because I'd done something to it. I hadn't, but once my attention was drawn to the offending device I leaned over it & flicked on the wall socket. Wouldn't you know it, suddenly it worked again!
