Someone might manage to annoy you without even trying, so don`t be too quick in your reactions. Make an effort to be positive rather than defensive. Try to read between the lines to see what their intentions might be; they may have your best interest in mind even if they don`t show it. Disruption could put the health of a group dynamic at stake. If things are moving too fast, see if you can find a way to slow it all down and get back to productive, healthy relations.
