Oh! I had to say one more thing: When I was a kid, when I came home and said "Thomas called me a name in school today", my parents would answer: "CONSIDER THE SOURCE!"
The first time they had to explain it -- Thomas, being the son of a single dad who drank too much and had a new girlfriend every week, was probably not a person whose opinion of myself I ought to respect, because he was a kid who probably had so much trouble in his own life that he lashed out at anything that moved.
I used that phrase a lot when AXH used to call me names. "Consider the source!"
And now I'm passing it on to you.
