At CVS today, Charlotte scratched my leg so hard she drew blood.  I don't know if it was a fingernail or a toenail; she was wearing flip-flops and thrashing around on the floor.  Charlotte wasn't having a temper tantrum, or being malicious, she just cannot stand in line like a normal human being.  Why stand quietly when you can flop around on the floor?  This is why she rides in the cart 85% of the time.
