Somehow a conversation with BuhBuh about bees turned into this.....
BuhBuh: What does 'Mating' mean?
Me: It means to make babies
BuhBuh: Can two boys mate?
Me: No it has to be a boy and a girl
BuhBuh: What about two girls
Me: Nope because it takes a boy and a girl to make a baby
BuhBuh: What if one of the girls looks like a boy
Me: No, because you still need boy parts and girl parts to make a baby
BuhBuh: But two boys or two girls could adopt a baby, right??
