Dumb

I have nothing to say to you

That's right. Nothing.

"sighs" I suppose so.

I'm sorry you feel that way. "shrugs"

"flinches back" That's not very nice.

"rolls eyes and ignores the insult" Is there something specific you needed help with?

Like what? I'm just being myself. "shrugs"

"smirks" I have a personality, it's just not one that you might find interesting or appealing.

"looks around" Maybe I am bored. Is there anything exciting happening that I don't know about?

"looks incredulous" I'm sure that's just a rumor. You know people like to make up things to get attention.

"raises eyebrows" That's not very appropriate. You should probably call the authorities if they're causing a disturbance.

"disgusted look" That is highly inappropriate and disrespectful. I will not tolerate such behavior. "ends the conversation"

I beg your pardon? I am just being myself.

"shrugs" If you say so.
