Adult Sheldon: People often ask why I was so resistant to getting a driver's license. My spotty history with motor vehicles was certainly a factor.
[flashback: Georgie driving Sheldon and Missy to the hospital:]
Sheldon: Please slow down.
George Jr.: I'm going eight miles an hour. A cow just passed us.
Missy: You're gonna hit it!
[flashback: George driving through a car wash with Sheldon:]
Sheldon: Make it stop!
George Sr.: It's just a car wash.
Sheldon: Do something!
George Sr.: It's just a car wash.
Sheldon: We're gonna die!
George Sr.: Just a car wash.
[flashback to Sheldon on a go kart:]
Sheldon: Why did I agree to this? I don't care for this at all.

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

Ms. MacElroy: Now, can anyone tell me why Melville shifts the narrative voice from Ishmael to Ahab? [Ms. MacElroy waits for somebody else to raise their hand] Sheldon.
Sheldon: I have a tummyache. I'd like to see the nurse.
Derek: A "tummyache"?
Sheldon: Yes, Derek, I have a tummy and it aches. Ergo, tummyache.
Derek: Ergo?
Sheldon: It's Latin, Derek.
Ms. MacElroy: Go to the nurse.
Sheldon: And to answer your question, the shifting point of view grants the reader a broader perspective of events than typically allowed by first-person narration.
Ms. MacElroy: Where were we?
Sheldon: And "ergo" is Latin for "hence," Derek.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Adult Sheldon: My mother eventually coaxed me back into a car with a trip to RadioShack. She knew I was nervous so she came up with an interesting distraction.
Mary: Baby, how about we play a car game?
Sheldon: I suppose. Can I make it science-based?
Mary: Sure.
Sheldon: I'll say an element starting with "A," then you repeat that and add one starting with "B."
Mary: I don't think I'll get very far.
Sheldon: Great. Then I'll win. Aluminum.
Mary: Okay, uh, you said "A" for aluminum. "B." Is boron an element?
Sheldon: Yes.
Adult Sheldon: It was the beginning of a new tradition. One that would eventually bring countless hours of joy to Leonard on our drives to work. Much like my mother, he never beat me.
Mary: I don't know an element that starts with "D."
Sheldon: I win. That was fun. Round two. Argon.

Dr. John Sturgis: [on the phone] So, there's no one who can lend you a car?
Meemaw: There is the church shuttle, but that just feels like it's the end of the line.
Dr. John Sturgis: Oh, I wouldn't say that. There's all sorts of depressing steps before the end. You've got full-time nursing care.
Meemaw: Bye, John.
Dr. John Sturgis: Assisted living.
Meemaw: Bye, John.
Dr. John Sturgis: Hospice.
Meemaw: Bye, John.
Dr. John Sturgis: Life support.
Meemaw: Bye, John!
Dr. John Sturgis: Pulling the plug. [chuckles]
Meemaw: Bye, John.
Dr. John Sturgis: Then... you make a miraculous recovery!
Meemaw: Great!
Dr. John Sturgis: But... the hospital bills leave you destitute!
Meemaw: Bye.
Dr. John Sturgis: Bye.

Dr. John Sturgis: [on the phone] Oh, my goodness. Was anyone hurt?
Meemaw: No. But now I got no car for a while.
Dr. John Sturgis: You could ride your bike.
Meemaw: An old lady on a bike? That's not cool.
Dr. John Sturgis: Really? Then I won't ask how I look on one.
Meemaw: You look great.
Dr. John Sturgis: I know. I just wanted to hear you say it. [Meemaw chuckles]
