People will treat you how you teach them to treat you.  What that means is that you set the tone… if people are ignoring you, you’re probably helping them to do that.  If people are engaged by you, you’re probably helping them to do that. If you’re a “cold fish”, then you’re probably teaching people to be cold around you.  So think about the tone that you set.  What you radiate, you attract.  People will treat you how you teach them to treat you.  Think about what you want to teach them in the first place.  When you think about that, you’re going to change your behavior to a way in which you want people to respond towards you.
