Oh, yes! I have days like that. I have to look at my calendar to even know what day it is and what I'm supposed to do that day. I pick up and take my grandchildren to school on Mondays and Wednesdays but yet I forgot that I was to do it this morning. I stayed up until 3 and then remembered. So I only had 3 hours of sleep. Fortunately I was able to nap today.
I get confused every once in awhile about where I'm headed. I'm going to pick up a friend but I turn to drive to my daughter's. I head for the store and then can't remember what I was going to buy.
Your post reminds me that I must get gas before I do anything else tomorrow.
