"But for guys like me this is not a fun youth. It gets better. I'd like to make one of those it gets better ads, for dumpy young guys. We could use a little help, a little encouragement. Just somebody on TV...listen man, I know it's tough for you man. You're vaguely heavy, with no face. You have zero value on the sexual marketplace, you feel invisible to the girls in school because you are. But it gets better. Because you all grow up. And you pretty much look just like this your whole life. And they don't. Their options start runnin out, really fast. And you're gonna be there. As long as you stay relatively employed and washed, you're gonne be AMAZING in your 40s! You're gonna be the branch that she can grab before she hits the ground! It's gonna be so great! It just takes time for her circumstances to match your looks. But it's gonna happen! It's gonna happen. When real sh i t matters, you're gonna be the sexiest mo th er *beep* er in the world! It's just time, that's all it takes. There's a formula to this. It's pussy + time over income, squared."
If that doesn't describe the situation between Mavis and Matt, then I don't know what does.
