Only got like 3 or 4 hours of sleep last night.  Had to go gather shopping carts for the first hour of my shift.  Actually at McDs for lunch.  Traded shifts with a coworker Friday so he could hang out with a friend and I could come in at 1600 instead of 1100.  At about 1700, my legs and feet decided to protest.  They began hurting and still haven't stopped.  I think it's because I pushed myself hard the 3rd time I was gathering carts.
