Hi Pat,
Not quite enough information to provide you with an objective opinion. That said, negativity is never nice, and should be avoided as much as possible. Sometimes, in a carefully planned way it helps - it's memorable. I certainly remember being "told" a few times by instructors over the years.
In my opinion, you have to have a chat with your instructor. Be prepared to take some relevant criticism, and be gracious when it comes. But state your unwillingness to accept meaningless criticism, or negativity. PPL training is serious business, but should be fun and positive too.
If you have specific examples of something which is disagreeable to you, put it forth, and perhaps commenters here will have thoughts. Be prepared for honest opinions though!
