Please notice that I'm not capitalizing those terms; by "young" I mean "younger than me and not yet married."
Familiarity breeds contempt?
In some wards, the boys and girls have been together since spitwads were being thrown during Primary. It would be like dating your sister.
Or so I've heard, but I don't think I believe it. Because I know an awful lot of married people who met at church. Including my wife and me.
I think the secret is for a guy to find a girl who is enough years behind him that she was never in the same class, so they will have no memories of seeing each other at their silliest.
