Basically yes, you are more than half way to a wonderful compatibility!! HOWEVER you should really get a 'compatibility report' done, whereby you could see all the other elements in both your charts......there will more than likely be other areas where your compatibility with each other would be reinforced..... Basically with sun/moon signs, you both see eye to eye on pretty much everything..as the old timers used to say, "The moon gets its light from the sun"...meaning, you both understand each other ANOTHER HOWEVER...Pisces & Aries are water and fire...IN GENERAL pretty tricky, but again, your moon/sun thing would be a help to your relationship...AND ONCE MORE you really should get a compatibility chart done; they will need both your names, dates, time and places of birth....make sure you get a compatibility and not a synastry chart; just my opinion by synastry charts don't seem to me to reflect the actual relationship; just my opinion!! PLEASE do yourselves a favor and get this done: you can go to any astrology site and they will email the report to you within 24 hours!! talk about instant gratification!! :D haha.. anyhow, best of luck............astrology is a VERY complex subject,,,,MUCH MORE to it than most people realize...if you can use it to understand yourselve and your other, more power to you!!!! Good luck.......I wish you'd let me know what you find out!!!!!!!!!
