"Boys don't wear panties..."

According to Lily: "Boys don't wear panties, they wear dirty pull ups." ::said with frownie face at the word dirty::

While rough-housing with Mommy on the couch:
Lily: no, no Mommy (shakes finger), we don't throw people. That's not nice!
Mommy: Oh, sorry. You're right. No throwing people.
Lily: we can go outside and throw basket balls. Outside. And we can bring out our buckets for dirt. Outside. But we don't throw people Mommy.
Mommy: You're right. How did you get to be so smart?
Lily: Daddy.
