Mixed signals

So, I e-mailed my boss two weeks ago and asked if he wanted me to work. Here's the response I got:

Wren, at this time we have our schedule complete up until the beginning of the spring semester. As far as moving back in your house early you would have to take that up with [ladyboss]. She turned in a list of names of who was returning early to work at Security to Student Development for early move in. It may be too late for you to move back early.

So I do e-mail Ladyboss, and she says she can get me into the house on the fifth even though I'm not working. So I call in today to get them to unplug my doors, and the boss I e-mailed above shows up to let me in. Guess what he asks?

"So, Wren, since you're here, you want to work a few shifts?"
