Thank God he never complains

That's one of the few reasons why Wily kept Protoman around as long as he did.

Unfortunately, to Protoman, "never complaining" meant "never telling anyone that I perpetually feel like shit, among other things". To be fair, he had no one to talk to...but when Megaman temporarily joined forces with him he still didn't "complain".

That was a slightly bad move on Proto's part.
