its a good chance its something you're doing to make him react that way. teachers have a lot to deal with, why would they go out of their way to have someone stress them out?

look at the difference between your own actions and some other peopels actions. I'd put money on it something you're doing is just getting under his skin and up till now you failed to realize it

if you really want to initate rapid change after you acknowledge it and process it around for a little while, speak to him on a personal level and tell him you acknowledge what you did to (unkowingly) get under his skin and explain how things are going to be different from here on out. guarantee you'll see an immediate difference in how he feels about you.
