Having your parents get very, very old. At first, it's rewarding to feel like you are helping them live at home. After a few years, you realize that they aren't deteriorating as fast as you thought they would. They just keep getting older and more dependent on you. Ten years later, your back has a permanent bend in it from lifting and bending over. Your fingers are split and calloused from changing a million adult diapers and you can no longer get the smell of poop out of your head. You have a hundred and sixty pound baby that has to be fed food paste, spits up and coughs in your face showering you with food particles and red koolaid. You social life is non-existent, no-one will even stop and visit anymore and you have a splitting headache from their constant yelling.
Eventually, you get so burned out that you wish euthanasia was legalized so YOU can escape the pain. But, it just keeps on coming. People should only have kids before age twenty five and after age sixty:- )
