leave no room for scandal; avoid actions that could be misinterpreted
Proverb warning against behavior that might invite suspicion, even if innocent. Literally: 'Don't adjust your cap under a plum tree (lest you look like you're stealing plums).' Used to advise caution in situations where one's actions could be misconstrued.
As the proverb says, 'Don't adjust your cap under a plum tree,' so I'll avoid counting money in front of others.
