In love
The beginnings are gentle, because the Goat appreciates attentions and the Rat knows how to give them.
Then the rhythms diverge: the Rat wants to decide quickly and practically, the Goat needs to be consulted and reassured. Quiet reproaches settle in on both sides. One finds the other inflexible, the other finds them too sensitive. Putting needs on the table, in simple terms, defuses these annoyances before they harden, and gives the couple back its warmth.
