Borrowed space deserves care that lasts beyond the hour it is useful to you.

A room you use briefly is somebody’s permanent place. Leaving it slightly better than you found it costs very little and is invisible to you afterwards, which is precisely why it tends to get skipped. The measure of how you treat borrowed things is what happens after they stop being useful to you.

Take a last look before you leave any space you did not pay for this week: chairs back, lights off, whatever you moved returned. Consider it part of the borrowing rather than a favour added on top.
