I'm pretty sure

The boys and I were sitting outside on the front porch after school today. They were having a snack and we were talking. We had talked about their days, and I started asking them if certain people were boys or girls. This is how the conversation went:

Me: Is daddy a boy or a girl?
Drew: Boy!
Me: How about Mrs. H?
Drew: She's a girl.
Me: Yep. How about Blake? Is he a boy or a girl?
Drew: Boy!
Me: Nice. How about me? Am I a girl or a boy?
Drew: Boy!
Me: What?! I'm not a boy! I'm a girl.
Drew: Are you sure?
