So, assuming you have no kids of your own currently, what you're saying is, you don't care about children, period.
Considering they're the ones that are going to run this show later in your life, you might want to revise that. I'm not saying you have to go out and date the first single mom you can find. But caring about kids in general is just the right thing to do. If nothing else, try to show them the ropes when they ask for questions, or for help, so they're not completely useless idiots when they're in control.
You know very well what I mean about another mans kids. I'm talking about taking care of another mans kids from a previous relationship. I love kids. I love my nieces and nephew, my baby cousins, etc... I'm always looking out for them and will always try to steer them in the right direction and be as good an uncle or cousin as I can be.
