M.K.
I've got way too many to list and usually I can't remember them - must be subconscious!! lol!! Although, I do have one that's absolutely ridiculous - I'm working in a humane society for about two months now. After about six weeks, it came up in conversation about the kittens having blue and pink collars. Well, duh, I never even realized why the different colors. Any time someone would ask me about a kitten, I'd go to their folders to look up the information. (Trust me, it's difficult to tell on a small kitten.) Anyways, I started laughing so hard at myself, I was almost in tears.
I've had so many "duh" moments over the years; and it's usually something really small and stupid - just ask my kids. I'm usually somewhat of an intelligent person!! Seriously!! lol!!
Great question!!
