Read it on Caferati
There's this self-pity in the "lonely slice of pizza", the "pain is filling up the cracks". But she makes her excuses "I have been playing host", "I'm doing fine", "elevator is full" and shuts the door on the visitor, rejects his unwanted sympathy.
The last but one paragraph doesn't belong here. It's a monologue in her head, of the paranoia of being deliberately avoided by others, that she would not be addressing out loud to the visitor whose sympathy she does not want. The rest of it is of one piece, telling the visitor he's not needed.
Nicely done. Was not at the Read-Meet, can you post that version here as well?
