When Everyone is Wrong

If you’re going to correct someone’s grammar, you better make sure that you’re right. Nobody likes being corrected, but everyone hates someone who corrects other people without getting their facts straight. This guy tried to convince the OP that Where have I been? was supposed to be Where has I been.

That doesn’t make any sense. It doesn’t matter in which context or tense you use it. You always use have with I. Don’t ask us why, that’s just the way English grammar works. But what’s astonishing is that the guy trying to correct the original commenter is wrong and he doesn’t even know it.
