I really enjoyed all my classes this year, and I loved all my professors too. They were very enthusiastic, helpful, and dedicated. It's been awhile since this has been the case, and as a result, I want to write each of them a thank you card, but I'm very worried that professors will take this the wrong way? I wrote thank you cards to select teachers who I really liked in high school, but I don't know if there's a different "culture" in college? I don't want them to misunderstand, but I really do want to thank them.
