Why am I selfish? Because I have had kids. How do I know this? Because a woman who has never had kids--and never will--got pregnant, had an abortion, and subsequently had herself sterilized so that she can never have kids because anyone who has kids is selfish: http://www.dailymail.co.uk/pages/live/femail/article.html?in_article_id=495495&in_page_id=1879.
Here's the thing. My kids aggravate me. Every kid aggravates their parents. Sometimes, it seems as though that is their sole mission in life. And you know what? I wouldn't trade having any of them for anything in this world. This shallow, incredibly self-absorbed woman can spout off all she wants about this subject, but she has no clue, and she never will.
