Who's the author of this quote?

[MMarceloE]

Hello, there! I can't remember who said it and I can't seem to find the exact quote online but it goes more or less like this:
"I never complain about being tired. I don't want people to think my Master is not kind to me."
Does anybody know the author of this quote?
Thanks in advance.

Hello Marcelo,

Sorry I wish I could help. I do like the quote though.
Hope all is going well for you in Brazil.
