I would like to adopt this fic and make it my brain canon :P
This is a much better ending than the episode.

“Leonard’s my best friend,” he appears to be trying to work something out from the way his eyes aren’t meeting hers, “and he has been for seven years. He’s certainly shared your general reaction on numerous occasions, but he’s never apologized for it.”
Broke my heart :( Oh Sheldon.
Great job :D
