Narrative:
I was practicing maneuvers with a student, when I noticed a potential conflict with another aircraft. I took the controls to begin maneuvering away from the other aircraft. The other aircraft matched my speed and attitudes. Eventually I opted to land at a nearby private airport. The other airplane landed directly behind me. When I asked the pilot what he wanted, he responded saying 'you should have been monitoring the frequency.' at no time before this situation occurred was my airplane in conflict with the traffic pattern at the private airport. There is no published frequency for this airport. The pilot of the other airplane violated crash fire rescue equipment 91.111, causing me to have to take evasive maneuvers.
