Oh jeesh, Best, I have worked very hard on distinguishing when to persist and when to walk away. I used to persist as a knee-jerk reaction in all situations. In other words, my natural inclination is to stand my ground. One possible explanation is that my mother was a holocaust survivor. Apparently that can give the offspring kind of a chip on their shoulder.
I've always been that way. As a junior high student I made a stand, after contacting the ACLU that I should not get in trouble for not pledging allegiance to the flag. That was during the war in Vietnam. Also I was one of only two girls who broke the dress code in that same school by wearing pants to school one day. All the others lost their nerve at the last minute. It felt incredibly weird not to have to tuck my skirt under my legs when sitting at my desk. That feeling persisted all day long. But we won. The dress code was re-written not long after.
