We have assemblys on Mondays, I volunteered to help. The job is to set up the chairs for the parents and seniors. It was quite hard because we put the chairs in rows of 6 and 3 chairs wide. The reason it was hard is we kept having to move them over or back. I made sure they were all straight by going up and down all the rows.
I showed use only what you need because I did not take down lots of chairs I took down the right amount of chairs.
