As much as she should be teaching manners and tidying up after the boys when she is out. I would not tell them off for pulling papers off crayons, I’d say ‘oh no we don’t do that cos you’ll ruin the colours’. I would never tell them off and tell them that it was unacceptable. That’s a bit far for a young child who probably didn’t know he was doing something he shouldn’t.She is probably that type of a parent who lets their children make huge mess with spag bol at the restaurant and doesn't bother tidying up after. I used to work as a waitress and we used to hate those types of customers. If I saw my child taking off papers from the crayons I would immediately tell them off and explain that it is not acceptable. Rebecca, teach your boys some manners before they turn into a plonker like their dad.
