That is beyond what is needed for security - I second riri, that was bad.......
Here is a question I have. When I was a kid, no one's parent's spent time at the school like parents do today. I am volunteering to teach 4 art classes in an Art masterpice program, I know parent's who volunteer to help in the computer lab, in the classroom, at recess etc. When I was a kid, no one's parents ever came to school. Except maybe to work in the cafeteria, cross walk, or something like that.
So, why are we turning out worse people??
