Not irrationally; there are numerous well-publicized incidents, such as child protective services being called for a six-year old playing unsupervised in their own front yard. Or, and I do forget the state (though I think it was Maryland), a state official saying that children under fourteen should never be left alone unsupervised for any length of time. When I was twelve, I babysat my little sister all day and made us hot lunches. Nothing fancy - just your standard packaged noodles or similar - but yeah, I knew how to use a stove safely.
