Hey, we're going to be late for our next class dude. We should go now.
We can't leave even if we're going to be late. We need to clean up our lab area first and make sure everything is where it's supposed to be.
Mr. I'm all set to start working on this lab.
Excuse me, but you're not ready. I've said many times that we were going to have a lab and you came in wearing a dress?! You know that you're not allowed to wear baggy/long clothes when doing a lab and two, tie your hair back please,
Who wants to wear safety goggles? I don't because I can do this lab without those over my eyes.
You need to wear them right now. if you don't , you'll get bad chemicals in your eye or even worse. Listen to me and put them on right now.
