Had a teacher like that, he was the absolute best. He's the reason I discovered my love of science. Guy had tenure and worked like he was a first year teacher, always had time for a student and did it all with a smile on his face. I'm sure he's retired by now, but man he was truly amazing. He would hang up your college acceptance letter on his wall like you were his kids, there were always hundreds covering the classroom by June. When my father told me the schools that accepted me only did so because they "are buy in schools that only wanted his money" (funny, I was emancipated, I guess he forgot even though he was the one who did the paperwork) he took all three and hung them in his classroom and helped me pick. Funny, I didn't know you could buy your way into Ivy League without having good grades, and I paid for it myself... I hate my family honestly.
