man: Who?
I: Nobody. It's just me.
man: Oh.. Should I know you?
I. No. I just told you, I'm a nobody.
man: But that's just sad. Can I help you my dear?
I: No. Am I looking like I'm needing help?
man: I don't know. Your looking lonely, don't you?
I: That's possible. Wouldn't you look lonely, after beeing left?
man: I've never been left. Sorry.
I: That's just okay. It's like Robert Frost said: In three words I can sum up everything I've learned in life. It. Goes. On.
