Change of Schedule

My FM caught me as I on my way to work last Friday and asked if I'd be willing to switch out my Wednesday 7PM class for a Friday 4PM class. That way, the person I'd be switching with would get Fridays off and I would get Wednesdays off. Would I? Of course! And it turns out I'm switching classes with a friend of mine, L. So I have tomorrow off and I'm wondering what I should do with it.
