The Law of Equality?

I hate math much like most of humanity. (I know! I know! The very idea that you may share any trait with me makes you want to crawl into a hole and pull it in after you. But, before you start digging, just think. After all, you too probably have a couple of eyes, only one nose, one mouth etc. and so do I...) The funny thing, though, is that I shy away from it when it IS required but insist on using it where it is not applicable.
Take this Law of Equality, for example. When someone says 'If A=B, then B=A', my mouth opens in a huge yawn, my eyes turn up and I keel over. All of which ought to mean that I will never apply this so-called Law in life. And then...
Back in my youth, someone said, 'Truth is Bitter'. First of all, I assumed that Truth = Bitter. You know how it goes. Most of us cannot recognize the truth if it ups and bites your nose, most times. Especially when it comes from another person and especially when it is about you. So, here was a nice and simple test for the truth. If you disliked what they were saying about you, then it must be true. If you liked it, it would be false. Ergo...whenever someone praised me (it happened rather rarely, yes, but still...), I assumed it was only flattery. Whenever they insulted me, I assumed it must be true. So, naturally, I grew up into this self-confident, assertive person who mumbled his way through life, practically apologizing for being alive.
And then, of course, Bitter = True. Which effectively meant that I had to ensure that if I told the truth of someone, I had to ensure that it also sounded bitter to him. NO 'You have bright ideas, but you need to be more meticulous in your analysis' and all that. Just 'Who gave you a degree? You ought not to have been allowed to graduate from fifth grade". There - THAT would be bitter enough to be true! Naturally, after a lifetime of speaking the truth, I am awash in friends - who scatter like a flock of birds, when you throw a stone, at the first sight of me.
Law of Equality, forsooth! Now you know why I HATE Math. It just does not work in real life, I tell you!
