 Hello? Hi, Mrs. Gonzalez. Sure, I can work at the store tonight. What time? 6 to 2? Okay, I'll be there. You're welcome. Lakeisha, I need a favor. I have three papers to finish plus a midterm this week. Can you take over that story? I'm writing for the student newspaper. I can give you my notes. I just don't have time to write it. I've got a couple of midterms and a paper too, but sure I can fit that in. Thanks so much. It's been so stressful to get everything done. Hey, don't worry. I'll send you my notes as soon as I get home. It's due on Friday. Thanks, Lakeisha. Hi, Lakeisha. I am so glad that I found you. What's up? I got my car towed to the garage, but I need to pick it up. Can you drive me? I have a shift at the store tonight from 6 to 2, but I can drive you over to the garage now. Thank you. Thank you so much. You're the best. Just who I wanted to see. Hey, what's up? Hi, Jew! Are we still on for dinner? Oh, no. I forgot. I took a shift at the store from 6 p.m. to 2 a.m. and I'm driving Pierre over to the garage to pick up his car right now. Can you meet me at work later and we can grab a bite to eat? Sure. I can meet you there. I'll bring some dinner. What about getting together on Friday night? Yes, that works for me. Great. Wait, didn't I hear you tell Amira you'd write a newspaper story for her by Friday? Girl, you are over-committed. You are indeed. You guys, I just like helping people. Is that so bad? As long as you're helping me first. The time can come out and this becomes m times the square root of 1 plus p squared plus m squared. And that tells you that for a particle at rest, the first shot. You have to stop saying yes to everything and trying to help everyone who asks. It's the same. We expand it in the other way. Let's see.
