With 7.5 billion so far and (unfortunately) still counting, adoption is so much a smarter thing to do than making more. Supply exceeds demand in many parts of the world.
I know as it's what I tell myself to try and feel better, a part of me just needs that experience though. I would blame it on hormones, but ever since I was little it's something I knew I wanted. I always wanted to be like my mom, so that could be part of it. I remember one time I was like 5 and my mom was waxing, so when she walked out of the room I slathered my arm with wax and by the time she came back it had cooled. I guess she thought ripping off cold wax was punishment enough for me.
