"I got a piece of your hair"

So my kids have quite good imaginations. And they really use their imaginations together... and sometimes they fight...
Example:
E: "I got a piece of your pants"
H: "SHE HAS A PIECE OF MY PANTS!"
--two kids run around, Hannah trying to get her piece of pants back.. and Emily teasing her----
Me: Hannah she doesn't have a piece of your pants she's just pretending...
---Quiet for a whole second----
E:I have a piece of your hair and I'm going to put it in Mommy's hair.
H: OH NO! MY HAIR!
Mom: Here you go Hannah, your piece of hair....
E: I have a piece of your hair and I'm going to put it in Mommy's hair....
H: OH NO! MY HAIR!
Mom: Here you go Hannah, your piece of hair..
--continued until they got bored of it... Once Emily realized I could quickly calm Hannah down about it, she stopped bugging Hannah. And they started playing "going to the mailbox"
(if you didn't get it.. no pants pieces or hair was involved in the above conversations)
I do love my kids soooo much. They really amaze me by their imaginations. Earlier today they were having a "sleepover." And 90% of the time they play really nice together and it's soo cute!
