That is very true. My nephews have face book to talk to grandma on! If i ask any younger friends ( will younger people who humour me)... about it i get the kinda look i would expect if i had just suggested communicating by roman wax tablet!
My mum uses fb, she’s 71, my kid mainly uses snapchat. My mrs had to set up a fb account last xmas because we bought the boy Oculus Quest (I refused on principle) she’s since used it for licking a few cats.. or liking? I’m not entirely sure how it works.
