Mars begins its tour of duty in your opposite sign on Dec. 19. Named after the Roman god of war, Mars can be very confrontational and combative when it’s traveling through this part of your solar horoscope. However, Mars is more passive-aggressive than in your face when it’s in Pisces, so expect to contend with a sea of sad sighs, forlorn looks and waves of guilt trips from your nearest and dearest. The best way to counteract the emotional manipulation will be to respond with some inertness of your own. Mars will be in Pisces from Dec. 19 to Jan. 27.
