Yeah, you think you already know but let me remind you of the rules because the first time your college aged daughter who is beautiful and elegant and brilliant walks in the house with a dweeby little wanna-be artist with a handshake that says "I'm a goober" you'll forget all the rules. You will drag your magnificent daughter into the bedroom and say, "What the pooh? He's a soft little fellow what are you doing and why do I have to feed him?"
Now that you've expressed your dislike for the tiny guy he's going to seem that much hotter. Artsey Romeo meets Juliet syndrome.
You're eighteen year old son brings home a Asian Gangster Girl with "CRIPS" tattooed on her neck. She has a beautiful smile but frightens the entire family. You drag son outside, "Where did you meet here?"
"At the rehab clinic where I volunteer on the weekends, Mom. And you'll love her kids. They are great."
You shake your head, "Son, this is a bad idea," and he just hugs you cause you don't understand.
"I've got it all under control Mom and she has a really beautiful soul". Gangster Juliet and Innocent Romeo.
You handsome football playing son brings home a smoking hot cheerleader who thinks the Pulitzer Prize is given right after the Grammys and says Will I Am is her favorite poet. You smack his helmet, "Are you kidding ? She's an idiot." Well because of your reaction you'll probably have grandchildren in the next year. Horney Romeo and Stupid Hot Juliet Syndrome.
So parents, understand, if you express any disapproval you will be pushing your child into the arms of the one you dread, the one you fear, the one you know is absolutely wrong for your kid. If you "forbid" them to be together, they will find a way to be together at all costs, even if they don't like each other that much.
The best thing you can do is shut up, smile and and pray. And maybe serve something for dinner that your child loves and they have know idea how to eat. Sometimes that works.
