Well, I'm used to talking to things that can't talk back. At least another person can look and sound sympathetic, or can give good advice. Sometimes people like just having someone to cry to, or someone to hug.

*She knows that's true, though she isn't really the type to cry in front of anyone, or to hug people*

Or..you can say what is bothering you, and we agree to talk about it only as much as you want, and then I can help to cheer you up as best I can.
