good impression of a Czech

Recently one of my students had to drop my class. He wrote me an e-mail, letting me know how much he enjoyed the class and how much he learned from me (now that I think of it, maybe I should print out the e-mail and frame it!). I was flattered as any teacher would be, but the most remarkable part of the message was when he mentioned that I made a good impression of a Czech on him. Phew! So glad I represent my people well. Wouldn't want to ruin the reputation of a nation!!! Better think of that next time I feel like chewing a student out... which I would never do, of course... not me. No Czech would ever stoop to that.
