You are insulted, because you are imagining that I've called you unimportant, which I have not. There is no one else here that arrived before you, that I must see to. Until you leave, you are my work, even if others arrive before you are through speaking with me. But I do not appreciate you hurting me by leaving my work purposefully unfinished; I find it very painful to be left, having only worked partway through an issue.

Do not use my pain to manipulate me; you do me a disservice.
