As I'm not familiar with that character, I will assume she talks like a baby all the time. I do know someone like that and I go out of my way to avoid her as she doesn't see why people won't take her seriously. I feel for ya. Confront your son and let him know that his life will be much harder if he sticks with someone who will not speak properly and how it reflects on his chances to get better jobs as networking between families of the management is a thing and that will prevent their inclusion.

One thing I learned a long time ago - Don’t get too excited about your children’s GF/BF. If you act like you love them they will eventually drop them. If you hate them or speak ill of them they could be drawn closer to them… Most relationships don’t last, don’t sweat it. In any case they are the one that has to be around them, not you.

That's funny! I'm American and very familiar with Little Britain, but sure not many are.

I had to Google who Vicki Pollard is. She is played by a man. Your son's girlfriend sounds like a man?
