How could you forget?

Being in a long-distance relationship, you quickly understand the atmosphere stemmed from video-calling on a laptop versus on the phone.
Sitting with my bulky headphone in front of the screen, we were in a semi-serious mood…
He: Wait, do you remember the first time you punched me? *half-jokingly*
Me: Umm, was it when you spent two months here? *tentatively*
He: No! You really don’t remember? *roaring with laughter*
Me: No? You tell me then!
He: Remember that time I had a Saturday meeting and went to a brunch place with a whole bunch of coworkers afterwards? I was surprised how much force you put into the punch!

Most of the time, I can’t recall the memory of me hurting my loved ones, physically or emotionally.
Unless the person makes it explicit, all the incidents would be a blur.

I’m always amazed at how people recall childhood memories before the age of 10. For me, there were fragments. Only those that made a huge impression stayed in my head.
Standing at the kitchen counter, I spoke to my mom who was slicing a ripped mango…
Me: Do you remember when I was in kindergarten, you punished me for not being able to memorize the home address correctly?
She: What? Did I do that? *genuinely surprised*
Me: Yes! You dragged me out the door without my shoes! *in disbelief*
She: Really? That must have been a few minutes only. *awkward*
Me: Well, it felt like an eternity! I was so afraid and ashamed that the neighbour would see me crying on the stairs. Out of embarrassment, I climbed up to the rooftop of our apartment and hid next to the storage.

So, all pains leave scars.
Then, why could not those inflicting the hurt remember at all?
