You won't like the barb that comes flying over the net when Mercury opposes Pluto on June 29th. You know that this person isn’t your match; that they're trying to score points by riling you up. In a perfect world you'd avoid having anything to do with this person, but at the same time remaining silent makes them look like they've hurt you and have the upper hand. What you need to do is trust that their actions will make them look foolish in the eyes of others and that if you give them enough rope they'll wind up hoisting themselves by their own petard.
