Sometimes I do that. It depends on my level of self-esteem which fluctuates. When I feel emotionally secure and confident, I can mentally identify that what they say has no real force to it in the material world and the reactions inside me are my own doing.
When I'm tired, worn out, or depressed, I tend to personalize things that happen "out there" and when I'm like this, I will definitely give in.
I feel a need to help people when they phrase things in a way that put them in a position of helplessness. Don't know why. My dad's the same way and very altruistic, sometimes to his detriment.
