I would not be so sure.
People differ not only in how they speak, but also in how they think, formulate ideas, process information, and argue. In astrology, one of the key indicators in this area is Mercury.
Its placement is traditionally associated with thinking and communication style. One person thinks while they speak: they need to say the idea out loud in order to understand it fully. Another needs to build the whole structure internally before they are ready to say anything.
Some people are comfortable speaking briefly and directly. Others notice ten different nuances before they formulate a response.
But Mercury’s sign is not the whole story either. Its aspects, house placement, and the rest of the chart matter too.
That is why the advice “you just need to communicate” is slightly overrated. Talking is not enough - you also need to check whether what was heard resembles what the other person was actually trying to say.
Sometimes asking “Tell me how you understood what I just said” can save an hour and a half of a perfectly good argument about something neither of you was actually arguing about.
The stars speak. The choice is yours.
