When my kid has a nice day
A cute plush
Crab rangoon
Seeing plants start to bloom
Friendly cats
Seeing someone embrace their curiosity about a subject
My stupid bearded dragon
Seeing someone clearly filled with joy
Younger people discovering a "retro" thing and thinking it's "cool"
Being able to answer a question because you have the niche knowledge to do so
Someone who is genuinely awed by sometimes you put a lot of time / effort into
Eating a juicy, crunchy, delicious apple that hits that craving just right!
Seeing a cool bug
There's more, but I'll stop for now (but lmk if you need a continuation).
