So tired today too. My boss said I didn't have to be at the cash machine today, but when no one's around I had to. 
I did have some enjoyable moments in the park, harvesting flowers for bouquets. A bit chilly, so not many bees and bumble bees out and about. Dew on the flowers, silence and just one other super harvesting flowers to sell by themselves. I made 3 bouquets and they were all gone before I went home. 
I had my break under a tree, listening to music and drinking my smoothie. Sun was shining and a breeze chased off most of the warmth, making it a wonderful break. 
My boss told me I could go earlier if I wanted, but I was managing the shop area... sweeping the floor in some places, helping customers. Then I thought I could go 5 minutes early, and went to tell a coworker, but a customer came in asking about nesting boxes for birds. So I got her one and helped her, then next customer came and I helped her. But then I left, and after clocking out, the bosses having lunch together, saw me leave so they'd know no one inside could open the cash machine.
I've done some chores and finished a task. Tomorrow I begin later, due to three coworkers leaving and I'd miss that otherwise.
I think I'll have an early night anyway, even if some brain function as returned... when I got to work this morning, the light was on (in my brain) but nobody was home...
