Why? I don't know.

My little sisters have this weired problem of pointing to and at everything with the middle finger. I have no idea why it started, I mean they've never done it before, but lately everything from reading a book to pointing at a passing dog has involved an older sibling or parent taking their hand and gently correcting the finger position. It caused quite a problem the other day when Tabitha and I were walking around outside and a nice little old lady decided to do the same. Tabitha looked at me and tugged on my jacket.
 "Look Sara!" She said and pointed, innocently yet offensively, at the Ladies pink shawl. The Lady's face turned from a healthy crisp pink to a deep red and she quickly walked away muttering, "Children nowadays..." 
Ohhhh Tabitha, the innocents of youth.
