I came late out of college once, jumped into the passenger seat of my mums car, started belting myself a in while saying “we need to get home I really need a poo” to look up and find, in fact, it was not my mums car
This isn't really quite the same thing, but I was so embarrassed and very upset.
Deep in lockdown, my husband was picking me up from hospital where I'd been keeping my friend company, sitting with her, while she had chemo.
Went outside to wait, and my husband's car pulled up, driver with grey hair and glasses in my peripheral vision, all familiar - hopped in and suddenly this stranger shouted "GET OUT! GET OUT!
GET OUT YOU STUPID WOMAN! ARE YOU FUCKING MAD?"
It wasn't my husband but the same model car and a lookalike driver.
And we were in deepest covid lockdown and he was collecting someone from the chemo unit, so might very well have overreacted. Of course I jumped out in shock and embarrassment. Husband was only a couple of minutes behind him.
It was a minor thing on the face of it, but I sobbed all night from shame, shock, my own perceived stupidity, and later, anger that he'd bellowed at me so aggressively. I can remember him baring his teeth. Was awful.
I just made a mistake. I mean, I was coming out of the chemo ward too.
I can't imagine being so aggressive towards someone who has made a genuine mistake.
Anyway. It's off my chest now. At last.
