Such is the way of dogs

“On his way the poor man finds all things against him;
The earth itself closes its doors to him.
You find him hated, though he does no wrong;
You see hostility but not its cause.
At the sight of a rich man you find the dogs
Turning towards him, as they wag their tails,
But if it is a poor wretch whom they see
They come to bark at him and bare their teeth.”

– The Arabian Nights (trans. Lyons, et al.)
