We all have sensitivities to the behaviors of others and it can be helpful to look below the surface of that dynamic. Our automatic response is generally to blame and judge the other person and then to attempt to get them to change their behavior. Why? Because we perceive their behavior to be the source of our irritation or upset. We want to decrease or eliminate our distress and the obvious solution seems to be to get them to stop doing what irritates us.
But wait -- while this might be an effective short-term solution, it doesn't deal with the fact that we have the hot button in the first place. Usually these sensitivities point to something much deeper in our psyche that has little to do with the situation at hand.
