Consider how you behave with a friend's dog for a fortnight. Fed at the right times. Walked whether or not you feel like it. Watched slightly anxiously for anything off, and taken to somebody qualified the moment it appears.
That is love expressed as maintenance, and most people are markedly better at it for a borrowed animal than for themselves. The body you are in has been on loan the whole time too, to be fair about it. Just a considerably longer fortnight.
