Sheldon: Leonard? Are you sleeping?
Sheldon: Are you ill?
Sheldon: Are you still depressed because you're alone, and no one loves you?
Leonard: I don't know. Maybe.
Sheldon: I want you to know that I'm genuinely concerned about your well-being.
Leonard: Thank you.
Sheldon: You're welcome. But it's still no reason to have your feet in my spot.
