Brew - I've seen the pictures of your daughter with her new puppy, and I can fully see why the boys want to keep her company... she seems very sweet.
I personally think you should give the boys the benefit of the doubt. Girls have good instincts, we can tell if a guy's trying to get one over on us, if they're genuinely being good guys or if they are trying to play Mr Sensitive. Your daughter can take care of herself.
I think it's very cool that you obviously care so much though.
