The next night at dinner, everyone is eating at the dining room table, but Lisa's older sisters suddenly gag and spit out their meal and complain that it wasn't cooked right.

Lynn Sr.: It's not my fault! The recipe is in metric, and Lisa usually helps me with the conversions.

Lisa: "Thanks to Lincoln, I'm out of the conversion game, except for converting beans to methane.

She toots hard enough to make the table bounce.

The rest of the sisters growl at Lincoln who gulps nervously and leaves the table.

Lisa: Hold up, before you all get mad at Lincoln, I think I can see what's going on..

Lori: Like what?

Lisa: You all just want me to do all the work you should already know. Luna, I've repeatedly told you that you should ease up on the music playing and study for your geomotry test. If you had any questions, I would have been glad to help you. But yet you continued to "Rock Out" as you say and wait until the night before to cram some studying in. It is not Lincoln's fault that you failed the test; it was your own doing..

Luna: That's way harsh dude..

Lisa: And father, do you not cook the same 7 meals for dinner every week?

Lynn Sr: Yes, of course..

Lisa: Well then, why do you need my help to convert things, if you cook the same meals every week? And I assume you were able to keep the family well nourished before I was born into this world, so its obvious you know how to cook. If you can't convert things, google it..

Lynn Sr: Heh heh...

Lisa: Listen, don't take this the wrong way; I love helping my family out in any way I can. But I realize now that if you all just want to use me for simple mundane tasks that you should already do, then I am afraid that I cannot be of any assistance to you...

The whole family looks nervously at each other..
