The two debaters of Numerology are here today, and though they approach communication differently, they can still spar with the best of them.
1, like 5, loves the spontaneity of life, while 4 needs the ability to plan it out and know the score. And with their headstrong views, sometimes the words come out too harsh or not in the manner that the other can understand. What both do excel in is writing down what they need and want (though one note may be shorter than the other).
Today, instead of contemplating speaking in words when you come up against a challenging issue, consider writing it down. Proofread (the 4 is good at that). And then send it across. You never know what topics of discussion it can lead to.
