Kennedy's thank you note

This last week, Kennedy asked me for an index card she could write on.  After a few minutes she said, "Mom, can I take this over to Julie?"  (Julie is Kennedy's friend Whitney's mom).  I looked at the card that was filled with several squiggly lines and asked why she wanted to take it to Julie.  She responded with, "It's a thank you note for Julie for taking me to pre-school today!"  This was the first week we have used the carpool system for getting Kennedy and Whitney to pre-school!  I thought that was very cute and conscientious of our little girl!
