This is about Sheldon growing up to a world that’s bigger than just him.

But no, when she says she woke up she means that she got out of bed that morning, discovered that she was out of coffee, walked across the hall into the boys’ apartment (which, by this point, was really singular, but more on that later) without knocking, and only went as far as the counter before Sheldon was handing her the coffee without a word. Then she walked out and back into her apartment.

“I ought to warn you he’s in his room. And Shelly does not like other people in his room.”    This doesn’t faze her in the slightest. “He’ll make an exception.”

She considers this for a moment, then points to the screen, “So that’s one of the Final Five?”   He looks positively outraged by that notion. “No, that’s an eight.”

“I believe he brought up the time we cleaned your apartment and you in turn divested us of our key. However, I argued that since you had apparently already invaded our apartment while we were gone, I might as well return the favor.”
