It happened again....

So, I was driving to work and I made a left turn and the lady in front of me was going really slow. I put my blinker on to get in the right lane. All of a sudden she moved into the right lane. I got back in the left lane and when I passed her, she was flossing her teeth very vigorously. I watched her in my rear-view mirror all the way down the street and she must of been steering with her knee and couldn't stay in the lane because she was using both hands to floss and wasn't stoppin' for nothin'. I guess for me, flossing is one of those things that you do in the privacy of your own home.
