Wasn't planning on updating until Friday, tests, horses, work, and all, but then I remembered I already had this next part written, so figured I'd drop it off with you guys and then get back to studying! So here you go!

Still only own Iris, Savannah, and Ada.

"Aunt Penny," Iris asked suddenly as the car pulled into the parking space near the apartment building. "What's a verb?"

"A verb?" Penny repeated, getting out of the car and opening the back seat to work on the two car seats.

"My teacher says that every sentence needs a verb, or else it isn't a sentence," Iris said.

"She's right," Penny said, helping the girls out of the car and heading for the lobby. "A verb is an action word. So whatever word in the sentence that tells you what the person is doing. Like now; what are we doing?"

"Walking up the stairs," Savannah chimed in.

"That's exactly what we're doing," Penny said. "So since we are walking up the stairs, walking is the verb in the sentence."

"So, if I were to look at Savannah and say 'I'll race you up the stairs', then 'race' would be the verb?" Iris asked.

"Yep," Penny said. "But I don't think it'd be very smart to…"

"Race you up the stairs!" Iris blurted, lunging forward.

"Not fair!" Savannah yelled, taking off after her.

"Be careful, girls!" Penny called after them. By the time she got to the fourth floor, collected Ada from Raj and Missy, and reached the fifth, Iris and Savannah were sitting on the ground, their backs against 5B's door. "Taking a little rest?" Penny asked.

"We are sitting by the door," Savannah said. "Sitting is the verb."

"Very good," Penny said. "Iris, can you take Ada while I unlock the door?"

"No need."

Penny jumped when the door opened and Leonard was standing in the threshold. "Hey. Took a half day in case you needed some down time after your appointment."

"Aw," Penny said. "Go on in, girls." She kissed Leonard lightly on the lips and carried Ada inside. The girls ran off toward Savannah's bedroom, and Penny sank down on the couch with the baby.

Leonard sat beside her. "How was your appointment?"

"We're cutting right to the chase, huh?" she said.

"Well," Leonard said, "I'm sorry enough I couldn't be there; I'd like to know how it went."

Penny nodded. "It was fine. Basically the doc asked me how I was feeling, how my relationship with Ada is, if my relationship with Savannah has changed, the last time you and I had sex, if I'd had this after Savannah's birth, blah blah blah." Penny shrugged. "Gave me a prescription, I can still breastfeed, so he expects me to have perked up soon."

"Well, that's great," Leonard said, putting a hand on her knee. "That's really great."

She smiled. "Yeah. She also encouraged me opening up to some of my friends, so I was thinking of meeting with the girls tomorrow and telling them. They've been pestering me to hang out, anyway."

"That sounds like a good idea," Leonard said. "Where are you going to meet them?"

"Well, definitely out of this building," Penny said, smiling at Leonard's relieved look. "You were right. I need to get out some more."

"Hey Mommy?" Savannah asked, her and Iris skipping out into the living area.

"Yes, baby girl?"

"We have a verb question," Iris announced.

"Are you still on that?" Penny said. "I thought little kid attention spans weren't that long."

"We were playing with the letters," Savannah said. "And I spelled out 'verb'. But Iris says I spelled it wrong."

"It's V-U-R-B," Iris said. "Right?"

"No, actually," Leonard said. "It's…"

"V-I-R-B," Savannah announced, sticking her tongue out at Iris.

"Nope!" Leonard said. "It's V-E-R-B."

Savannah wrinkled her nose. "That's stupid."

"I don't make the rules," Leonard said, shrugging. "The verb in that sentence being 'make'."

Savannah was frowning. "What's the verb in the sentence 'Your mommy was busy doing your daddy'?"

"Well, 'was' is a verb," Leonard said. "And so is 'doing', so…wait, what?"

Penny was looking at Leonard with raised eyebrows. "Savannah, where did you hear that sentence?"

"Uncle Sheldon."

"Of course," Leonard said, putting his hand over his eyes.

"How does somebody do somebody?" Iris asked.

"Well, it's like this," Leonard started.

"Mommy was going to be an actress," Penny said. "You know, be on the TV? Well, when you're acting, you're pretending to be somebody else. So I guess Uncle Sheldon means that I was doing – imitating, pretending to be – Daddy here." Penny wiggled her shoulder slightly, then cocked her head a little, frowned, and said "I'm a physicist. I think about stuff and write some of it down."

Savannah and Iris giggled. "You're good at doing Daddy," the blonde announced.

Leonard coughed to hide his amusement. "Wow, Penny," he said. "I didn't think you'd be doing me in the middle of the living room with three children present!"

Savannah cocked her head. "What?"

"Nothing, sweetie," Penny said, swatting Leonard on the shoulder.

"I don't understand," Iris said.

"And we hope you don't for a lo-o-ong time," Leonard said, patting her on the head. "Why don't you guys go wash up and we'll get you a snack?"

"Okay, Daddy," Savannah said, grabbing Iris's hand. The two girls skipped off toward the bathroom.

"They joke about getting married when they grow up," Penny said. "I think I might half believe them."

"Nah," Leonard said. "They're basically being raised as siblings."

"Speaking of…" Penny said, "do you think…do you think Ada will be close with them? Are Savannah and Iris too sisterly? Will that hinder Savannah and Ada growing close?"

"Raj and Howard's relationship didn't prevent him and Bernadette from finding each other," Leonard said.

Penny blinked. "I know you're joking," she said, "but that actually makes a lot of sense."

"Well, in that case," Leonard said, "I wasn't joking. So…" He looked off in the direction that the girls were headed in. "Do you think they'll remember that whole 'doing someone' thing when they get older?"

Penny thought for a moment. "I'm trying to decide if I hope they do or not. But you're the scientist…will they?"

"I think Amy's the one you'd have to ask on that," Leonard said.

The girls came out of the bathroom, Iris drying her hands on her pants. "Iris," Leonard said. "Towel."

She frowned. "Aw, man."

Savannah watched her head back toward the bathroom. "Mommy, Daddy, can I get a dog?"

"Hey," Penny said, sitting up and adjusting her hold on Ada, "we said we weren't going to have that conversation right now."

"Okay." Savannah nodded. "Then can I have a board like Iris and Aunt Gilda?"

"Maybe a puppy," Leonard said, glancing at Penny.

"We can talk about the dog," Penny said at the same time.
