I like being alone...

Nash: I'm going to be dead in a few hours. Your secrets couldn't be safer, unless you're keeping them from yourself.

House: I like being alone. At least, I convince myself that I'm better off that way. And then I met someone at a psychiatric hospital of all places. She changed me. And then she left. We're better off alone. We suffer alone, We die alone. Doesn't matter if you're a model husband, or father of the year. Tomorrow will be the same for you.

Nash: But yesterday would have been different.
