Everybody loves my parents, especially my mom. I wouldn't seriously date a person if they hated my parents for any reason. If a girl got to the point in the relationship where she met my parents, family, etc, it means the relationship is quite serious -- my answer is based on the fact that I'm not local, but I don't understand this Vancouver social norm of seeing the other person's parents three days after you started dating...
I've never seen a marriage/long term relationship last when one partner hated/disliked the other spouse's mom, dad or family (if the parents are still together, etc).
