Why it’s so much fun
These two fire signs are a trine apart, and being together tends to feel like a vacation. Leo loves being the center of a good story, and Sagittarius loves going somewhere worth telling a story about. They’re both generous, both optimistic, and both likely to say yes first and check the calendar afterwards. Laughter does a lot of the heavy lifting.
There’s also room to breathe. Sagittarius needs freedom, and Leo, secure in being adored, can usually grant it, as long as they’re still the person Sagittarius comes home to with all the news.
One honest remark too many
Sagittarius tells the truth the way other people sneeze, with no warning. “That haircut’s a bit much” is a passing observation to them, and it can ruin Leo’s week. Leo responds by going grand and wounded, which Sagittarius finds overdone, so they make a joke, which makes it worse. This can loop for a while.
The other thing to watch is who’s minding the boring stuff. Rent, dentist appointments and the parking fine can sit unopened, since each is quietly assuming that’s somebody else’s department.
Keeping it alive past the trip
Sagittarius can add one sincere sentence after the joke, because Leo will hear it and melt. Leo can ask for reassurance directly, without staging it. Divide the dull chores once a month, out loud and fast, before you plan the next adventure.
Two fire Suns don’t guarantee that either of you can sit with someone who’s sad. A watery Moon in Pisces or Saturn contact might do that work, and it’s worth looking for what supplies the stillness, because a lively relationship still needs some.
