I wasn't surprised to hear that I wasn't the only one who got a Halloween costume idea from our department meeting. Here are a few. I'm sure there will be more:
The Ineffective Teacher
The Explainer Who No One Understands
The Teacher Who Never Listens
The Teacher Who Thinks She Is Good
The Teacher Who Doesn't Know Names
The Teacher I Cannot Defend
The only problem with these costumes is that even with a mask, the person wearing it will be easily identified.
