Walked into the men's room

This morning, on the way to work, I felt really tired - overly tired. I got into work, pinged my friend, and walked down the hall to meet her for coffee. She met me. We chatted outside the restrooms. I said "I just need to run in here" while I grabbed the restroom door. Too bad it was the wrong door. It was the door to the men's room. I turned to walk in and she said "uh Cathlynn..." at the same time that I recognized I was in the wrong place. Nice!
