You've guessed Virgo, Libra, Leo, Cancer, and Sagittarius. So you've burned 42% of the possibilities. There was a really good chance to guess it with five choice. Sagittarius is correct.
Here's what I found out about people who are Sagittarians:
Sagittarians are optimistic, lovers of freedom, hilarious, fair-minded, honest and intellectual. They are spontaneous and fun, usually with a lot of friends, and are perhaps the best conversationalists in the zodiac (maybe tied with Gemini)
Of course, I also found THIS about Sagittarians:
Sagittarians are Isolated. Why don't we just leave them alone so they can be happy? I wouldn't say that they need to be alone--private and isolated is necessarily a wrong thing, but to be a person who seriously wants nothing to do with others — as does the typical Sagittarian — I have to say, it's a bit of a bore after a while. And Sagittarians? That's what's wrong with you: you're boring. You're so into your own personal world of wonder that you forget the simple things in life, like friendship — or relating to another human being altogether.
So it looks like I'm hilarious, fair-minded, honest, spontaneous, fun, lots of friends and a great conversationalist who is completely self-absorbed and has no friends or human relationships.
This is why I hold no stock in astrological predictions. Whatever you want to "prove" with a given person, you can find enough glimmers in any and all signs to say, "See? Fits you like a glove!"
Several sites I just perused mentioned that "we Sagittarians" don't like or want long-term relationships. Just don't tell my wife of 50 years this.
