Adult Sheldon: Paige made me realize that maybe I wasn't the loner I thought I was. Maybe I was a social butterfly, or a social animal less horrifying than a butterfly. Get it off the screen. But the point is, I was becoming a people person.
Sheldon: You again?
Paige: Well, hello to you, too.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

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.

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