I have someone in my life who does that. I learned just not to respond with anything that counters her thinking because she will either attack (with what she proudly thinks is her debating skills) or come back with some disming statement to the countering thought.

I learned early on not to take things personally from a mom who did nothing but take things personally. Observation helped me learn then personal experience & the more confident I became in myself the less personal I felt about things too. Understanding that it was them with the issue not me....though I think self-confidence does play some role in it also.

However in my analytical mind when someone does say something I always analyze it to see if there is any part of it that I might want to apply to myself personally to make any improvements that actually might help me.
