We were invited out for a meal to meet our son's girlfriends parents and we sat there for some time, feeling very uncomfortable, when both of her parents, and my son and his girlfriend, were busy on their mobiles. It is not only rude, but embarrassing. So it's not only young people! We've since learnt that her parents constantly post photos of their meals, or their glasses of wine on social media with the message 'out for a lovely meal'!! Hence, I loathe seeing photos of other people's meals and drinks now!!! I just don't understand the reason - is it to show off, to make others jealous, to show what fish and chips looks like, or perhaps to tell the burglars you are out so they can break in??!!!!
