Who Does That…

I work for a small, family owned company. They are very easy going and very flexible. Our dress code has always been business casual. You know, jeans and a nice shirt.
We are a growing company and 6 months ago we hired a Front Office person. She is a young lady in her late twenties. She started out actually over dressing for our company and then she slowly started to relax. Well last week she relaxed just a bit too much for any of us. She walked in wearing a Superman t-shirt. But wait, there’s more! The t-shirt had a cape attached to it! I kid you not, she came to work in a freaking Super Hero outfit!
Maybe I’m just getting old, but who does that?
