A good command of the language even if she doesn't know what it means.

I made homemade caramels today, it's become a fall tradition.  Peyton got to help me and was very excited about that.  When the caramels were all done and I was sitting at the table wrapping them she came in and said very sweetly to me, "Mom, I sure do appreciate you doing all this."  It melted my heart.  She quietly walked out after I told her I was glad to do it and I loved her.  She promptly walked back in and said, "What does appreciate mean?"
