My 19 year old daughter has been corresponding with another girl who is 23 for the last 4 years. They communicate over the internet and by phone. I have never met the girl and this girl has now invited my daughter to come visit her in NY for a few days after Christmas. My daughter really wants to go to experience all there is to see in NY but I'm a little leary since I really don't know this girl. I have asked my daughter tons of questions about the girl, which she answered but I still don't feel right about her going. I know she's 19 and I guess I can't stop her if she really wants to go but she has asked for my permission. Am I being an overprotective mom?
