["I'm feeling a little down since my wife will be gone for the weekend.", "That's unfortunate. What are you going to do to keep yourself busy all weekend?", "I don't really have anything to do! I will be all alone here, so I probably will sleep in."]
Sleeping in should be a positive thing! Take this as your time for yourself and relax.
My wife is going to be gone for the weekend. I'll be all alone and with nothing to do.
