I'm also a Sag, and I love being one. I'd say it's true for me, but I also have a few capricorn influences in my chart, so I can be reserved about expressing my enthusiasm. I'm a quiet Sag lol. But I don't think I'd want to be loud anyway.
But I can't stand leos, even though we're supposed to get along. Every leo I've met has been so self-centred, and that kind of behaviour truly annoys me. I've only met two Geminis, but I've found them to be too unpredictable (and occasionally moody) for me. But I LOVE Aquarians, they're hilarious, intelligent and so creative. I seem to get along best with Aquarians, I understand their quirkiness.
