I'm with you on the "have pets not kids" train. When I was in my teens my mom predicted how many kids me and my sisters would have. For my younger sister she said two, for my youngest sister she said ten (lol), and for me she said none, but I would have a lot of pets.
At the time, I was young and bought into the whole "girls are supposed to get married, have babies, clean the house, etc" thing, so I was actually offended by what my mom said.
But as an adult I realize, like most of my mother's words that I scoffed at when I was younger, she was absolutely right. (Though neither of my sisters have kids either, but we're all in our twenties so I suppose there is still time for them!)
