Some people are seemingly raised by wolves or something with no manners, social graces or appropriateness. Had a woman and her grown daughter over for dinner once, the sandwichmaker made a lovely meal and these two twits had the audacity to put their phones on the table and carry on texting even laughing to themselves over some text talk they were having with some unknown person.
FFS if you can't have someone's full attention when they are a guest in your home, well, I was just baffled, I suppose I don't interact much with this younger generation, not sure I want to.
