Little Bundles of Joy, right?

I have 4 nieces. My oldest sister has three girls and my other sister has just recently had her first girl. My family was totally expecting to have at least one little boy by now with all the kids that were coming into our family. But no, we have not had a boy and aren't expected to for a long time. My brother and his wife are having they're first child and we were hoping to be a boy but when the ultra-sound came around we weren't at all surprised to find that it will be a girl. this doesn't really bug me that bad but it does seem that this is an awful lot of girls that we have. Why is my family cursed/blessed with so many girls? Besides the obvious fact that it's just how the X and Y chromosomes happened to work out there has to be some reason. I was thinking about this and then remembered that more than 75% of my cousins are male and so I guess it was time that our family start having more girls. And then I also thought about the kind of people that my family are and how we would be with boys hanging around and I realized that it would be even more hectic than it already is. The boys would be raised to be crazy adventurous people. The men in my family are all hyper-masculine so this boys would be raised with the typical I-have-to-be-tough-and-can't-cry type of attitude. While all of this is generally how lots of boys grow-up it would be to and even greater extent at my home. It is now clearly a good thing that my family is very femininely populated.
