You are being a bit hard on these kids mate, these young girls have lives too. Good luck to them looking forward to a night out, getting ready, feeling and looking good about themselves, fair play to them.

I would imagine if you were able to spot and know they lived in your area you have been looking at them in other ways too !

Wonder would you take an invite, maybe that's the problem you don't !
Get of their back and let them enjoy themselves. Their youth is short enough.
