Maybe by and large guys like to talk to girls, but guys don’t like to talk to guys and girls don’t like to talk to girls. This would make a 2 chain model look

Maybe by and large guys like to talk to girls, but guys don’t like to talk to guys and girls don’t like to talk to girls. This would make a 2 chain model look bad I think. Maybe try a longer chain? i.e. “Bob liked Alice, and Charlie liked both Alice and Diane, so maybe Bob will like Diane” (Ik this is heteronormative — sorry)
