It's a ridiculous and extreme example but it actually did happen. I was going skiing quite often at the time though so maybe it didn't have the sticking power it would've normally.

In general, without some kind of trigger my ability to remember specific episodes is nonexistent. The OP talks about this too but those times when you have to give 3 fun facts about yourself or when someone asks my hobbies are moments of of existential dread because I genuinely have no idea what to say.

I realised recently that there are whole years of my life I'm basically missing when I think back. Like I know where I was living, what job I was working, and my general circumstances, just not anything specific I actually did.

I have come back from week long international trips, having arrived by plane on Monday or Tuesday, and by Thursday someone will ask me what I did last weekend, and I'll draw a blank, and the social pressure of not having an answer and not wanting to pause for a whole minute to exercise my memory to reconstruct the last week will make me say something like, "nothing much, you?". It's that by the second or third day of being back in my routine, I forget what it was like outside of that routine, feel so immersed in it day-to-day, so unless I remember that I did have a disruption I won't really remember anything...
