Here is here:
If your parents are old fools and don’t understand anything anymore, you’re an adult – get in the wheel and take responsibility for everyone.

Mark Twain: “Support it! When I was fourteen, my father was so stupid that I could hardly bear him. But when I was twenty-one years old, I was amazed at how clever this old man was.”

So if your parents are old fools and don’t understand anything anymore, just grow up.
