Prepared to be told IABU.
Having coffee with a relatively new friend, I said something about making Christmas dinner, she then said that she 'couldn't even make cheese on toast'. I was visibly gobsmacked and as it turns out she really can't cook anything!
She was really offended that I was so surprised, and told me she'd always been too busy to learn. I've offered to help her with some basics but she's ignored my message and cancelled our DS's playing together 
To not drip feed I was really shocked, going 'what not even. ....' and questioning what her kids eat probably a bit too much.
But really, wouldn't you be shocked if a 40 year old couldn't cook anything at all?
