Street smarts and big ideas
Opposite signs swap what they’ve got. Gemini gathers facts, voices and details, and can talk to anyone about anything. Sagittarius looks for the big picture, the meaning and the place you’ve never been. Gemini can point out when a grand theory doesn’t quite fit the facts. Sagittarius can point out when all those facts don’t add up to anything. Oddly, both tend to find this delightful.
This is one of the freer pairings. Both need room, both are curious, and neither wants a schedule. A week might include a language class, a spontaneous road trip and a long argument about religion in a parking lot. They’re often great friends first, and they tend to stay that way.
Know-it-all against know-a-bit-of-everything
The clashes usually have to do with certainty. Sagittarius will state a view as if it’s been handed down from a mountain, and Gemini will immediately find the hole in it. Fun for a while. Less fun when one of them is tired. Sagittarius can get preachy and Gemini can get snide. Neither is above winning the point and losing the evening.
Their real risk is that nobody stays with anything. Plans are big and details are thin, the deposit’s been forgotten, and the visa’s gone out of date. Each can also treat a real emotional need as an interruption, so a tough patch might be handled by booking flights somewhere.
Landing the plane
Agree on who’s the grown-up for what, and take turns. Before leaving on the next adventure, ask one plain question: “Is there anything we’ve been avoiding?” Let a good idea be good without having to be either the final word or the punchline. Say you were wrong now and then, since both of you find it very attractive when the other one does.
The opposition between these Suns tells you there’s something to learn, and doesn’t tell you if you’ll stick around for it. Look at the Saturn contacts between you, like Saturn square Mars, for how you handle what’s serious.
