Last semester I gave a talk to a high school family & consumer science class about my job, and of course to keep high school kids interested I came prepared with some interesting pictures.
I was at a school thingy tonight and talked to the teacher about next year after her group was done presenting.
"We got so much out of your talk! In fact, we talked about those bedbug pictures for weeks." Here the teacher paused, staring off into the distance. "Weeks."
One of the students piped up, "You'll show those next time, right? Those RULED!"
So I may have scarred the teacher for life, but at least I know I got through to the students!
