These are the chairs in the classrooms where I teach this term. They may be covered in bajillions of germs, but they're comfortable.
But sometimes these little adjustment thingies stick and the chairs get locked into uncomfortable positions.
Some are stuck down so low the students have trouble writing at the desk.
Some are stuck leaning forward so far that students have to sit on the edge of the seat.
And some are just crooked.And one time last semester, when the teacher sat down on one, it broke right of its base and teacher and chair crashed to the floor. The teacher and students were so shocked that no one could move. Eventually, after the laughter abated, the teacher asked the students if anyone had taken a picture of her on the floor. No one admitted to it. Then again, they never admit to texting during class even though they obviously are. So if you ever see the video of me on YouTube, let me know, okay?
