[b]High School:[/b] - No eating inside the classroom. - Make sure the projector and the lights are turned off before leaving the classroom. [i]There are others, but... they are too many to mention.[/i] [b]College:[/b] - Just make sure your phone is on silent. Feel free to use it as long as it doesn't make a sound. Hahaha. I love my college. They even allow us to eat food [i]inside[/i] the classroom. XD Whether it would be finger food or other food like pasta, rice, etc., it's all good.
