Look, YOU DON'T WANT TO BE A TEACHER unless you are extremely patient and don't have a temper. I am working with middle school kids this week in a science camp, and I was so glad when my day was over that I didn't know what to do!
You may want to listen to Jess, cause Middle school kids are WORST! I did a gig for the school board doing break / fix work on PCs and they are some badd assed kids!
