Free time.... what is this?

Now that I am full time in practicum, teaching almost the whole day I am down to working only one day a week. And that leaves my evenings.... free. I know, crazy. What a concept. I usually get home from school pretty tired. Those kiddies wipe me out. Many nights I have no desire to leave home, but now that I'm getting used to this whole routine I have this desire to do something in the evening. But it's been so long since I have had my evenings free that I hardly know what to do with myself. Tonight I watched a movie, tomorrow I'm going to Pam #3's. Of course I do have some planning to do every night, but I do most of that at lunch time or after school so by the time I get home I have little to do. It will be so different next year once I (hopefully) have my own classroom, because there will be a lot more to do. But for now I guess I'll just have to figure out what normal people do in the evening. Any suggestions?
