I have this whole issue with Boyfriends/Girlfriends and Holidays. When I was young my parents let both of my sisters bring the boy toy of the week home to celebrate the holiday with the family and it always seemed so fake. Like I'm supposed to wish some guy I just met a Merry Christmas or something. He's just met me, I've just met him and he's only there because he want's to bang my sister (it's true and we all knew it). It just cheapened the whole thing. When I was old enough to date while living at home, I just avoided the whole thing unless there was a get together and even then I kept it brief. It just makes me uncomfortable. When my wife and I were dating/engaged I used to spend the Holidays back east with her, so I got to know her family but by then it was serious and I was in my 30s. My older brother seemed to pick up on the same thing and did the same as I, he kept the visits brief to non-existant and never allowed them to interfere with the family. I should probably ask my Dad why he let my sisters do that.
Consequently, while my youngest (13) doesn't date, my oldest (16) isn't having her boyfriend over for the Holiday. He's been invited to the New Years get together we are having, but I have an ulterior motive behind that. She was invited to his house both tonight and tomorrow, but I nixed that plan. He's a nice kid, but holidays are for family. I guess those Christmases from my youth left me with a bad taste in my mouth for the whole thing.
Sorry for the rant.
