Star Trek: Deep Space Nine, Season 5

[Odo has interrupted Bashir's holosuite program seeking advice.]

Bashir:
What is this all about, Odo? You didn't come here to talk to me about women. [Odo looks away] Did you? [realizing] Aaah. This is about "Bedroom Eyes", isn't it?

Odo:
Who told you about her? Kira?

Bashir:
Nope.

Odo:
Dax.

Bashir:
Actually, it was Miles.

{Odo groans in embarrassment.]

Bashir:
[continuing] If people are talking, it's only because they care. You put on a good front. But anyone who really knows you can tell that you're lonely. If you're interested in this woman, you have to let her know.

Odo:
I can't.

Bashir:
Why not?

Odo:
What if I— What if she—

Bashir:
Rejects you? She might. But you can't go through life trying to avoid getting a broken heart. If you do, it'll break from loneliness anyway. So you might as well take the chance. If you don't, she'll move on and you'll never know what you might have had. And living with that is worse than having a broken heart. Believe me.
