You connect mentally from the very first conversation. Getting each other just clicks.
A conjunction means one person’s Mercury and the other person’s Ascendant are about 0 degrees apart. On its own it counts as neither harmonious nor challenging. What the labels mean.
Why the first chat goes so well
The Mercury person’s mind is drawn straight to the way the other person presents themselves. They notice how you put things and what you left out, and they’re curious about it. The Ascendant person feels understood at the level where most people only exchange small talk, and they tend to say more than they planned.
The Ascendant person’s birth time has to be known for this to appear. Being only a few minutes out won’t matter much, but a guess can move it off entirely.
Being described
There’s an interesting side effect. The Mercury person often has words for the Ascendant person: a description, a theory, a nickname that sticks. It can be delightful to hear yourself summed up so cleverly. It can also get tiresome if you start to feel like a subject of study, or if your partner tells you what you’re really like when you’ve just told them something different.
Meanwhile, the Ascendant person might be so responsive that the Mercury person doesn’t notice how little they’ve revealed themselves.
Keeping it mutual
Check who’s asking the questions. If you’re the Ascendant person, turn it round and find out what your partner thinks about when they aren’t figuring you out. If you’re the Mercury person, hold your theories lightly, and let the other person surprise you.
A quick connection in conversation also tells you only that you talk well together. It’s a great start, and most things you’ll need to know, such as whether words turn into actions, take longer to learn. Keep having the long talks, and start paying attention to what comes of them.
