Sisterly Love

I was vacuuming the carpet today while Katelyn and Adelyn were playing in Katelyn's room.  I went in to check on them and this is what I hear from Katelyn as I approach (in her sweetest "mommy" voice), "Adelyn, will you please leave me alone?  Please?  I would really appreciate it.  I really would, I promise I'd appreciate it.  Please?   Will you please leave me alone?  Do you want a hug before you leave me alone?"  I then peak my head around the corner to see what is going on.  Katelyn proceeds to hug Adelyn then say, "Okay, it's time for you to leave me alone now.  Thank you!"  Curious what Adelyn would do, I lingered a while.  She promptly turned herself around and crawled away just as Katelyn had asked.  Then the kicker, Katelyn yells (in her not so nice "mommy" voice), "HEY- ADELYN- GET BACK HERE NOW!!!" and then grabs her feet to drag her back....
