[ ghost's hair is a touselled mess. she is looking at kaveh. kaveh thinks - she has finally looked up. ]

Well, Ghost. What sort of architect would I be if I were only ever optimistic?

[ is what kaveh says. but he is smiling as he leans in. he plucks a little strand of ghost's hair that's escaped the cavern of her hood. gently, he tucks it back behind her ear. ] I'll revise my position, then. I was being imprecise. The absence of sadness is apathy, in the sense that apathy is a void. You fill the void with something else, and it will be filled with something else. When there is no sadness, there can be guilt. When there is no sadness, there can be envy. When there is no sadness, there can be joy. You can fill that void in with any other emotion. You do not need to be happy when you are not sad. You are not beholden to happiness. I think emotions are messy like that.
