Right now? No, I've been thinking about it a lot, especially since my brother became a father almost a year ago now. The way I feel it is that my life is my own, and I want to be able to do with it as I please. A child makes that impossible. Or, in other words, I'm not 'mature' enough to settle down, declare 'the next 20 years of my life I'll have a dependable income, be a decent role-model and always be there for my children if they need me', because that's what I expect of a parent.
My own parents are awesome, far better than many others I've met (and I know I'm biased, thank you), and as long as I feel that I can't be as good as them, I won't do it. Either I'll do everything I can to make sure that my kids can have a happy childhood and grow up to live happy lives where they have all the opportunities I had when it comes to making choices, or I won't have any at all.
