Re: Hmmm :(
She can use a PC and her smart phone - but it is interesting that she will always avoid anything technical with "I don't understand technology". In a house where meal times are often discussions of technology and science.
My sister does something similar. I've never quite figured out why, but I've got a theory. She is a phenomenally intelligent woman who learns almost by osmosis with zero effort, but she plays dumb constantly.
My theory on the matter is that it's a reaction to the bullying and isolation she experienced fairly early on as her intelligence started to become obvious to those around her. It also probably doesn't help that her best (and, for a significant portion of her late childhood and most of her teen years, only) friend is a bit of an airhead who can't keep up in intellectual conversations.
