Pressing right on the d-pad seems to give a random response. One time I'll reply positively, another time I may say something negative. I'm not sure what determines the response. I came upon some guys. They were like hey, what's up man, how you doin? I pressed right on the d-pad and my guy said something like hi, how are you? and then everyone around me wanted to fight for no reason. I don't get it.
