I've NC for this, as i find it embarrassing!
Just 14 year old's table manners are awful. Gets food around his mouth, shovels it in. He's had fixed braces fitted which he says are responsible for opening his mouth with food in, but his manners were pretty bad before.
We have told him and told him and told him. We are not shy about pointing it out.
I feel despairing. Why does he get it?
