Here is how I responded to a recent birthday well wisher:
Thanks for the birthday wishes. Have you seen my glasses?
I really don't feel a day older. Ugh! My knees are killing me.
Age really is a state of mind. Can you turn the TV up? I can't hear a thing.
I try to stay young by keeping up with what young people are thinking. Hey! You Kids, Get Off My Damn Lawn Would Ya?
Besides, I can't really be that old. When I was twenty-five, John McCain ran for president. Now he's running again. See, it hasn't been all that long.
