My mother taught me about "self-fulfilling prophesies". What I took away from this wisdom: don't seek psychic advice, don't consult with mediums, don't expect to fail, and don't read horoscopes.
So during my childhood I did not know my "sign", One day while goofing off in biology class, a fellow student asked me my birthday, after I answered the question he proceeded to comment about Libras. It was the first time I had heard the word. I still think very little about my sign and it always catches me off guard when a curious friend, colleague or strangers asks me what mine is.
Now imagine my surprise when people begin asking me about my children's signs! I don't know. I do not even care or give any validation to the question. I shrug my shoulders and say I don't know, and I try to keep it to myself that I REALLY do not care.
