Sorry Mommy

So, we're walking down the stairs and I accidentally drop an ear of corn.
I say "Karli, quit throwing corn down the stairs!"
She says "sorry mommy"
I look at her and say "did you really throw corn down the stairs?"
She says "NOOOO" :D :D <<huge grin
I say so "why did you say sorry?"
She says "sorry mommy I won't do it again."
I said "you didn't do it in the first place"
She says "yeah, and I won't do it again either."
