Paige: Your neighbors let you hang out with them?
Sheldon: I'm basically the social glue of our floor.

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: I may have promised Paige I wouldn't tell my mother. Thankfully, Missy didn't. I don't know what lip gloss flavor says "mature," but that would be my sister.
Mary: Paige?
Missy: Where is she?
Sheldon: There's a note. "Sheldon, thank you for letting me stay here, but I have to go. I'm happy you're doing well. I need to find that for myself somewhere. I hope I can. Your friend, Paige."
Adult Sheldon: After a few frantic nights, Paige showed up at her mom's. They had a lot to figure out. Being a parent isn't easy. I know I made life difficult for my family. And my own kids do the same to me. Just yesterday, I had to take my son Leonard to the skate park, like a regular park isn't bad enough. It's safe to say, having children is challenging.

Sheldon: I can relate. A young lady brought chaos into my life as well today.
Missy: What happened?
Sheldon: Paige was visiting the university and got mad that I have college friends and she doesn't.
George Sr.: You're drunk, Sheldon has friends. This a crazy-ass dinner.

Adult Sheldon: For many college kids, waiting in line for concert tickets is a rite of passage, and I was no different. Except, instead of rock and roll music, my concert was a lecture on black hole topology. Instead of a stage dive, I would dive into knowledge. Instead of guitar-shredding solos, I would witness universe-shredding hypotheses. And instead of a charismatic front man dazzling the audience, there would be... well, actually, the exact same thing.
