Already have a job for next year

I have already scheduled a sub job for next year!  I didn't even know it was possible for that to happen, but a teacher put in for a personal day (I am pretty sure he is taking his daughter to college that day) and I am on his preferred list.  When I received notification, I snatched it up!  I am so ready for this summer, but I know I will be ready to get back at it in August!
