Penny doesn't follow politics but she knows she doesn't like the recent changes to the credit card offers she's been receiving. Predatory credit cards had kept her in shoes for years now. She is sadly looking through her sad offers when Leonard and Sheldon come through the door. Leonard is apparently scheduling another colonoscopy. Penny follows them up the stairs so she can listen in. Misery loves company.

"There isn't very much room... It'll be really tight... I can't relax just because you say 'relax'! I can't make 2pm. I have a job... Fine, I'll work something out. I love you, too."

Leonard put his phone away with a heavy sigh.

Sheldon smiled, "I am looking forward to meeting your sister! When will she arrive?"

Penny perked up. Another Hofstadter! Meeting members of her neighbors' respective families was always an intriguing and surprising...

Fuck it, it was hilarious. Now that she and Leonard were no longer dating, she could just sit back and enjoy the show.

"Her plane arrives tomorrow at 2pm..."

"I'll pick her up at the airport!" Penny knew she sounded too eager.

Leonard gave her a wounded look, "My family isn't a side show act for your entertainment."

"Of course not, Leonard! Your sister is a brilliant woman who is doing very important work with... with..."

"Diabetes," supplied Sheldon.

"Diabetes," Penny continued, "and I am looking forward to meeting such an extraordinary woman." And if I bring some popcorn and cotton candy with me to help enjoy the show, sue me.

Sheldon gave Penny and condescending/approving smile, "Penny is right to be eager to meet someone so remarkable and, being your sister, no doubt Cassandra has a high tolerance for nonsensical and banal conversation."

"Cassandra can be a little... abrasive."

"Like your mom?" Penny asked, a little concerned.

"Oh, no! Nothing like my mother," that was a relief, "My mom is a trained psychiatrist. Cassandra doesn't have her people skills."
