It was raining so hard today that it took me twice as long to drive to work.  Buckets and buckets at 7 am.

Me: So today the plan is to--
Student #1 walking in: Sorry I'm late.
Me: --go over literal equations again and then play some review basketball.
Student #2: WE'RE GOING OUTSIDE?
Me, heavily sarcastically: Yeah, it's pouring rain outside, it looks like an excellent day to go outside.
Student #1: OHMYGOD, MRS. S, don't do that to me!  Do you see my hair?  The rain is the reason I was late in the first place, I couldn't get it to work in this weather, and now you're making us go outside!?  This isn't fair!
