I went to the store after work this morning.....
I was talking to myself trying to remember what I needed...
a stock guy saw and I think heard me because he looked at me.
I said good morning to him.
He said it back and asked if I was finding everything ok.
Told him yeah, just trying to remember what I needed, and did a, little thing I do with my hand like a fluttering motion with my hand from my head outwards (i probably made a face too with it).
That made him chuckle and he said oh ok with a smile.
