Odo and Quark in “A Man Alone”

Odo

I'll never understand the humanoid need to... couple.

Quark

You've never "coupled"?

Odo

I choose not to. Too many compromises. You want to watch the Karo-Net tournament, she wants to listen to music, so you compromise: you listen to music. You like Earth jazz, she prefers Klingon opera, so you compromise: you listen to Klingon opera. So here you were ready to have a nice night watching the Karo-net match, and you wind up spending an agonizing evening listening to Klingon opera.
