I don't know if it's a good thing or not. I just have never wanted kids and periodically I come up with yet another reason why I shouldn't.
This just came from observing that I'm not a 'nurturing' type. In fact, if I sense that someone wants me to be all nurturing and caring or expects it, then I just get pissed instead. And that's how you raise messed up kids. Point being: I shouldn't have kids.
