It's always disheartening to hear that parents don't accept their children for who they are. For example, a gay brother and sister have conservative, homophobic parents that would be horrified to find out the truth.

I assume this means the parents think that the guys are in one room talking sports and the girls in another, doing girly sleepover things like makeovers and pillow fights.
