I have so many happy memories, luckily. It's lovely thinking about them, but also sorrowful we won't make any new ones, especially when I won't have any with my own future family/children.
But from the top of my head…
A cat climbing on me whilst sitting on a slide in my grandma's apartment complex's playground in Hong Kong.
The times my parents held my hands to swing me as a kid.
This past summer, sitting on the grass drinking cider and snacking on fruit with my parents on a breezy summer afternoon. Another happy memory was painting with my parents in a park, also a cool summer afternoon :)
The times my dad and I completed the newspaper's sudoku & crossword puzzle pages together whilst commuting.
Random complements lol - most memorable was an old lady saying I'm beautiful in the toilets haha, that day we were celebrating my dad's birthday (the queen had just died a few hours earlier too, rip)
