Thank you for teaching us this year on such short notice Mr. Sheahan. I'm very sorry your physics classes tend to be quiet, and that many of us are too shy to speak up most of the time, but many of us appreciate the work you put into class, operating as if you've worked at this school for a long time. I can clearly tell that you are super invested with a bunch of the topics we've covered this year, and I'm sad that I won't get to talk to you more and take more classes with you after my graduation. Good luck in your teaching career, Zach
