Guitars don't require food and water, and you don't need to clean up after them.
Well, having been a kid yourself you should know what kids are like. Look back as far as you can and ask yourself one question... Would you have enjoyed being your own parent?
I wouldn't want to be my own parent, I'm as sure of it as I'm sure that cake is delicious (while probably hazardous to my health at the same time D=). I must have been such an nuisance when I was four, I would hate to have to put up with myself O_o
Well, that's the easiest way I can possibly think of the imagine what having children must be like. I mean, sure, I'm the most awesome person to ever walk the face of the Earth, but I don't think I would have enough patience to put up with some of the stunts I pull... like the grilled cheese incident! If I had been caught, and I was somehow my own parent (like Fry being his own grandpa... that'd be weird O_o), I would soooo kick the crud out of myself.
