Strange haircut, kids squabbles

I took 2 1/2 inches off today.  Felt good. I think it looks good to if I do say so. The strange part was the stylist, not my hair. After some small talk about my kids and Christmas plans, "Stand By Me"  came on and my stylist started singing to it. Then dancing a little. While she was cutting my hair.  This struck me as rather odd. But she did a good job nonetheless.

My kids fight and I'm not sure what to do about it. Usually I tune out but there's probably a better approach.  This morning was a late start day at school and fighting broke out about some hairbands. There was a lot of screaming, tattle taling, and door slamming. I told both girls they were grounded. But that doesn't seem to help much.  I admittedly have very little patience for listening to arguments and tattles.  And when they start up, I inevitably find myself wondering what the price of tickets to Chicago is at the moment. To send them all to Grandma Workman.
