The previous 2 installments probably stand out way more, but in rereading I'm taken by the sweetness of this page. Jane finally has a moment's relief that she doesn't have to hide her feelings anymore -- only to have it yanked away immediately!! Sucker! Fool!!
I don't know if the line about spitting in her food read very clearly. It was to suggest Marigold's co-workers all hate the boss too, and don't think very much of her birthday treats.
But back to Jane - we've only seen one example early on of her rejection angst, but the tactic was clear: eject to avoid further embarrassment. What would happen if someone she really loved did this to her? Would she.... hate them? Is love conditional like that? Is it possible the feeling that's building in her is a mixture of both extremes?
