I’m like you, although I’m not bad at math. I could never remember my parents’ birthdays, still can’t. I get my son’s birthday confused with his mother’s because one is Sept 13 and the other is Sep 20. I didn’t know it was a condition, though. Getting older makes it worse.
This is no exaggeration -— I was probably 12 years old before I could remember my exact birth date. My birth year ended in a 1, and my birth day was a 2, and I could NOT keep it straight. I still have trouble getting my ss number straight. It’s crazy. I’ve shown up at weddings on the wrong date, because I absolutely KNEW I remembered the date correctly, but I hadn’t. It’s maddening. I’m no good at navigating, either. I could write a story or an essay with making few, if any revisions, but I have to check my cheat book to get my younger son’s birthday on the right day. I passed the mathematics portion of my nursing school entrance exam, by taking the advice of someone who told me to go to the back of the test booklet and attempt to do some of the trigonometry problems, because you get points for making an attempt. My daily chemistry quizzes were always duds, because I’d put the decimal points in the wrong places. I studied my butt off and prayed to God, and got the highest grade in my class on my (multiple choice) chemistry final. If he hadn’t watched me take it as I say right in front of him, my instructor probably would have thought I cheated.
