It's a bird, it's a plane, no it's a baby...
X always represent nothing or a representation of the unknown (as in a mathematical equation). But imagine what a double X can do to two eagerly awaiting parents...ok for those who don't know, a double X chromosome in a baby signifies a princess in the making (my wife is already telling me how much I'm going to spoil her...) Yes! we are having a baby girl!!! And as much as they (the girls) will steal attention when they are born, she seems to have taken all the attention even while my wife is carrying her. A close friend said that a baby is like a parasite, "sucking" away the life of the host which in this case is my poor wife.
