When you meet "the one" have her yell as loud as she can and if you don't get a sharp pain in your ears, then she's good. Also, always look at her mom because that is who she will slowly become. Try to call her bad names atleast once a week. That way when you really mean it, it's not as harsh. Invest in a good TV/entertainment system and you're good to go.
Nevermind, ask Sam. He may have a better idea.
