Today I'm allowed to indulge into a little bit of melodrama. Bittersweet. Yes, I'll laugh at myself afterwards.
But let me quote Longfellow:

Ships that pass in the night, and speak one another in passing,
Only a signal shown and a distant voice in the darkness;
So on the ocean of life we pass and speak one another
Only a look and a voice, then darkness again and a silence.

When they do to you what you've done to others, is it fair?
Or is it ironic?
Keep playing the game people, that's all we ever do. And it's sad, and it's wonderful, and you can't run away from it. Love it or hate it, at least it makes you feel alive.
