Thank you guys for your reply. I really appreciate it. I guess I have known all along my decision (which is to change the teacher), but just needed that shove of confidence to get to it. I would likely be changing to the day where she does not teach at the store... yep, I know her schedule really well due to our "chats". In my culture, we always try to avoid confrontation and she is very much elderly whom I have to give my due respect, so I would have to try to reduce as much damage as I can.
