Another Odd Arrival At Work

I am walking into the building and see a nice young lady is holding the elevator for me. I get on the elevator and head up to my floor. I am a gentleman and allow her to exit the elevator first. We then start to walk to the door to get in. She holds the door for me so I can use my pass key to get us in. PRoblem is I don't have a pass key, and it turned out neither did she. So we go through the HR department to get in. I ask her why she didn't have a key. Turns out she is a freelancer as well. Just one of the odd things about being in such a big office. So many people that you don't know.
