I have remembered my age incorrectly at least twice in the last couple months. One of the times I was driving my little brother in law (14) somewhere and he brought up something about how I was 23, and it started about a 15 minute argument in which I claimed I was 24. I completely thought I was right until my wife corrected me later that night when I told her about it. I am 23. I am 23. I am 23. She made me apologize to her brother. Ha!
Once I mentioned Gumby around some people who aren’t that much younger than I am, and they said “who?”
It is very common for me to report that I’m a year older than I am. When I was young I was the youngest kid in my class - a year younger than almost everyone else. Since I hated this, I often fibbed and said I was older. It was a habit so long I still sometimes misreport my age.
For me it was my first spider vein, which I found last year. I’m 33.
Also, when I started having kids, I’d find myself rattling around the house at 3 or 4 a.m. after a feeding because, hey, I was up - I might as well do chores. It didn’t matter that I’d only gotten 3 or 4 hours of sleep. Dammit, there’s stuff to do! Or, I’d stay up just because I could be alone in a quiet house for a few minutes. My grandmother, who was a total insomniac, used to do that. You could wake up at any time of night and find her cleaning or just puttering.
