Well, I think that it's just stereotypical to group signs together and assume we're all alike. I am a virgo and I was born on my mother's birthday. She kept a spotless house, and I am very disorganized and really need a housekeeper. She was extremely critical and always saw the glass half empty, and I always see it half full. I think part of the reason is that the planets shifted a few days sooner (or later) on the year she was born, which would explain me having more Libra tendencies than her even though we were born on the same day.
One thing I will say, my mother gave her honest, blunt opinion whether you wanted it or not. I'm more wishy-washy (Libra, sign of the scales) and care too much what people think of me to speak up....which means I get run over A LOT and she NEVER DID! I miss her!
BTW....Capricorn that hates virgos.....I hate Capricorns. Funny, because we're supposed to be compatible....but I disagree with that 100 percent! I can pick out a capricorn a mile away, and usually go in a different direction to avoid them. UGH!
