I really hate being the mean Sub, but since I'm very young the students try to take advantage every chance they get. I usually start the day off as being nice...but as the day progresses I stop caring about being the nice sub and become very firm. Today I was burnt out by the kids 2 hours into the day...than eventually at the last 30 minutes of school instead of doing their "fun activities" I made all of them to sit down and read quietly. How does everyone else handle these situations? I have to Sub for the same school tomorrow...and I'm already dreading it.
