Your girls who come home rolling their eyes are unrealistic snobs. They either need to
1. Come to terms with the fact that those type of boys will not be able to match wits with them
2. Go out with a different type of boy who can match wits with them.
If they are looking down on the boys then they are not machshiv the sacrifice of worldliness for torah, and have no business marrying a learner. So I vote option 2. I hear YCT grads are worldly and mature.
