I don't want kids.
This is the part where all the women of the world say, "Ah! But you're 28 years old! You will; your biological clock will start ticking, and there you'll be, cooing over every infant in a 2 mile radius!" OK, sure. I'm sure this is true for lots of women, a complete 180 degrees at some unforseen time in their lives. And I'm not ruling it out. But I've never had any interest in having kids of my own, and babies make me squeamish, so we'll just leave it at that.
