You can take the boy out of the country...

For thirty-one years I went to work at the university every day in what I considered business casual.  Dress shoes and pants, a button down shirt and a sweater.  A few weeks ago I went back to the library.  I was wearing sneakers, jeans, a t-shirt, work shirt, and hoodie.  I was also wearing a backpack.  A student looked at me and asked: "Do you work here?"

I'm guessing it's the gray hair.
