I dunno. Some signs are assholes bc they're insensitive (Sags) ...and some can be assholes bc they ARE sensitive. (Cancers)
For some reason (and this doesn't apply to everyone) I'm drawn to water signs (Pisces, Scorpio, Cancer) to protect them bc they're sensitive. My mom is a Cancer. Other fire signs (Aries, Leo, Sagittarius) bc we have the most in common. My best girl friends have always been fire signs but I'll usually butt heads with male fire signs. Too much ego. My best friend is an earth sign (Taurus, Virgo and Capricorn) but they are kind of hard for me to deal with bc they're so f*cking ANAL and critical of other ppl. Sorry guys

Air signs (gemini, libra, aquarius) are my opposite and I really don't have that much experience with them. I've never had any bad experiences with them bc they're likeable ppl but I don't have any memorable experiences either.
So there's my experience even if you don't believe it. I don't change the way I live my day to day life... just observe. I wouldn't treat someone differently bc they said they were a certain sign.
