I do not have kids. I got sterilized (had my fallopian tubes removed) in my mid 30s. I never really felt the urge to have them, and the idea of having them became more and more of an icky thought. I am a sleepy person who wakes up at noon on weekends. I’m messy and forget the laundry in the machine. I’m self centered and like to spend what I earn on me, or choose when I feel like gifting and giving to others. I’m picky, I like to find things exactly how I left them, and I don’t like sharing with people who aren’t my husband. I’m not a bad person, I just understand my behaviors and realize that I don’t really have a responsibility to change as long as I’m child free. Add to that the fact that I have so many hobbies, a close knit group of friends, and a bunch of pets - I never feel bored or lonely and I know it’ll only get better with age. Kids just never factored in.
