Is it normal to be this swayed by a teacher?

Ok so all my life I've been pretty hard headed. Teachers never meant much to me and all. But this year I had this sub teacher come in half way through the year in my history class. My original teacher wouldn't be coming back. She got in a car accident with a drunk driver. We all loved her a lot because she was a great teacher. But then this sub comes in. Well call him Mr. K. Mr. K was an awesome teacher. He literally made learning history FUN when it was originally my least favorite subject. He told us all kinds of interesting things and I truely believe he is a genius at dome level. After a few weeks in class I learn he's 24 and lives on my street. My friends and I were all really happy about this because we never wanted to forget him. Mr. K would teach all my classes if I could chose. As weeks went on, Mr. K started telling us things nobody else seemed to know. He told us the meaning of life was relationships. I thought about it, and I totally believe him. After that point, everything he said, no matter how stupid, I couldn't help but believe. He started making my question things I'd never questioned before. He started swaying my political views, not directly but just by talking to the class about it. It's sorta starting to get like I don't think for myself while he's talking. He's a really funny guy, too, which is part of what makes him a great teacher. He sometimes makes fun of my friends, though, and they think it's mean but I think it's really funny because he never makes fun of me. Everybody loves Mr. K, it's clear by the 30 posters on his classroom wall that say his name and talk about how great he is. I've made him one too of course. But it's coming to the end of the year, and I know he'll never teach me again, and I think I'm a little too upset about it. I seriously don't know if its ok, please nothing mean! IIN?!
