Mary: Anyway, I just wanted to check in and see how you're holding up.
Brenda Sparks: Working extra hours, being a single mother. Living the dream.
Mary: Want me to give you a hand straightening up?
Brenda Sparks: Sure. You got a bulldozer?
Mary: Maybe we just need to get your mind off things. Why don't we go out this weekend, have a girls' night?
Brenda Sparks: Really? Mary Cooper's gonna show me a fun night on the town?
Mary: Yes.
Brenda Sparks: Where we going... bingo at the church?
Mary: Not anymore. [chuckles]

Mary: Shelly and this college stuff is killing me. I... I never went to college. How can I prepare him?
Brenda Sparks: Mary, if that kid is smart enough to have colleges wanting him already, he's got to be smart enough to figure it out.
Mary: Maybe. It still hurts to hear him say he wants to leave.
Brenda Sparks: I bet. On the other hand, I'm worried my Billy will never be ready to leave.
Mary: Oh, of course he will.
Brenda Sparks: Damn. Smoking, drinking, lying. You're covering all the sins today.

Mary: So, George is mad at me, and Sheldon is mad at me, and... honestly, I'm mad at me, too.
Brenda Sparks: Will you please give yourself a break? All that you do for that family, I am surprised you didn't crack years ago.
Mary: How do you handle it all?
Brenda Sparks: I'm sitting in a chicken coop drinking a wine cooler at 11:00 a.m.... clearly, I don't.

Mary: Hey, Brenda.
Brenda Sparks: She didn't want you to walk her in?
Mary: No. How about Billy?
Brenda Sparks: Oh, I walked him in. Found his homeroom. Explained that "homeroom" is different than his room at home. Still not sure he gets it.
Mary: Tough day.
Brenda Sparks: Yeah.
Mary: You want to get some coffee?
Brenda Sparks: I was thinking vodka, but coffee will do.

Adult Sheldon: Like a virus, heartbreak can also spread. Once it does, it's hard to contain. In some cases you can try to reboot and start over. But it makes you appreciate those early days, when your hard drive was clean... and the world was full of possibility.

Meemaw: Well, let's get into it. What happened? If it's another woman, she's a tramp, and you're way prettier.
Brenda Sparks: No. Although sometimes I wish there was. Then I'd have someone to be mad at other than myself.
Meemaw: And here I thought this one was gonna be the sad sack.
Mary: Mom, that is enough.
Meemaw: Oh, there's my little killjoy. [both laughing]

Adult Sheldon: As long as humans have been on Earth, they've had to contend with viruses. And as long as I've been on Earth, I've come up with fun ways to avoid them.
[flashback:]
Dr. Linkletter: I've heard so much about you. [offers hand]
Sheldon: Apparently not how I feel about shaking hands.
Adult Sheldon: I wear personal protective equipment...
[flashback to Sheldon putting on mittens at the dinner table]
[flashback to Sheldon wearing an astronaut suit in his bubble:]
Mary: You come here right this instant.
Adult Sheldon: ...and I was social distancing before it was cool. But in the early '90s, a new type of virus became prevalent. One that no amount of hand-washing could stop. A computer virus.
Sheldon: Oh, no.
Adult Sheldon: But let's back up and begin this story in a simpler time, before an insidious infection had upended my life.
