Have you ever had somebody ask you want your sign is? It's like a cliche, a pickup line at the bar. Or, people believe that their signs make a difference in compatibility. I'm a Virgo, so they say Capricorns, Tauruses and Virgos are good signs for me. Also, Pisces, Cancer and Scorpio. I don't know if that's true. I know two of my best friends are Libras.
There are traits that people in certain signs have. Like us Virgos are sometimes very analytical and can live inside our heads a bit. Or Leo's like to be the center of attention, the big stars. Leo and Virgo are not compatible, or so they say. I don't think that's the case.
I think we can be compatible with any sign, provided we know and understand the person we are entering a relationship with. If each person understands the other and their traits, and there's give and take, it can work for them. I don't believe in absolutes. There are shades of gray.
I used to laugh at astrology. You see Horoscopes in the newspaper and just know they are pretty much B.S. Today you will have success at work if you are a Virgo. That's not necessarily true. Those horoscopes are pretty much for entertainment purposes.
But, an astrologist who really knows what they are doing can use the stars to help a person understand when it's best to pursue business ventures, relationships, buy a new home and all of that. There is something to all of it, and some rich and influential people understand that.
So, I guess I can understand why "What's Your sign" can be a question people get asked when they meet. It can give them a basic understanding of a person, but your sign isn't all you are. Staying away from somebody because of their sign may not be a good move. That person could be your best friend or more. You never know.
