It might have felt that way, but I wonder if your projecting onto the neighbor? How do didd the neighbor outwardly make you feel uncomfortable? There were several acquaintances I’ve had that would naturally put their hand over their mouth when I had a major block. It actually caught me off guard and i would stop and point out their odd reaction. That conversation helped all of us as I didn’t feel pressure to speak fluently, and they stopped reacting that way.
