Snatching Kids

Taking other people's kids is a behavior that I will never fully wrap my mind around.  Why in sam hell would I want to kidnap someone else's wretched little monster?  That would require me feeding it, clothing it, entertaining it, educating it, and listening to it cry.  The precious, precious freedom I enjoy now would be no more.  Who goes out of their way to make sure their life is encumbered?  Is it really that serious?  I'll just wait until it's my turn, thank you.
