New you, new crew! With firecracker Mars hovering in your eleventh house of social networking today, you’re keen to participate with a fresh posse. The only catch? A few of your old friends could get prickly when they realize you haven’t invited them to join. How you respond lays the groundwork for the future. You don’t have to cut them loose, but you’re also not obliged to bring them along for the ride. If you’re the one being “left behind,” don’t throw a hissy fit. See it as a chance to spread your own wings and soar.
