Joy: Seeing a street musician performing, and realizing you've seen that same musician performing in that same spot before.

Sorrow: Being able to remember the name of a song, and what the song is about, but not how the words or melody go at all.

Joy: Finding an old poem you wrote and completely forgot about, and reading it through fresh eyes.

Sorrow: Being in a call with your friends, where they want to keep talking, and you don't.

Joy: Realizing that you have friends.

Sorrow: Realizing that you have friends, and you don't know why.

Joy: Going to the cinema to see a great movie, and forgetting which world you're in.

Sorrow: Eating a silent lunch with your family, thinking you should strike up a conversation, and realizing that you've nothing left to ask them.

Joy: Looking at the story you've orchestrated, and appreciating the little intricacies, that nobody else but yourself will ever find.

Sorrow: Feeling, for even a moment, that perhaps, you should leave your family, not because you'd be better off without them, but because they'd be better off without you.

Joy: Being blessed enough to be able to travel far, and wide, and see all these slices of the world.

Sorrow: Having someone wrong you, and then apologize to you, because once they've apologized, it means they're “forgiven,” and that you can't hold their wrongdoing against them to justify and validate yourself with anymore, not because you want to make them feel bad. In fact, you don’t. But just because you want, in the case that everything goes wrong, to feel like you’re still in the right for once.

Sorrow: Looking at your hands after they have written this list.

Sorrow: Feeling a lump in your throat.

Sorrow: Knowing you're alive.

Joy: Knowing you're alive.
