how to make a chatbot that gets annoyed at a user

You can do this with a Self script. You would need to check the difference between the current and previous input.

Something like,

if (Date.difference(conversation.input[-2].getCreationDate(), input.getCreationDate(), #millisecond) > 5000) {
    return "I'm glad your back, I thought you left.";
} else {
    return null;
}

what about the chatbot not answering my questions or playing a game with me because it is annoyed.And if I say something to it ten

times the chatbot would say I guess I can forgive you.then the chatbot would answer my questions and play games with me.

How would I do that?

You could do this with a Self script, or using the "think" tag on a response.

the chatbot really would be acting like a girlfriend acts if you stay away too long.

I need the full code.i need to see if it is what I need?

I do not want to pay, forget it.
