Have you met these people in life?
Who think everyone else is doing it wrong,
And they are the only ones who can do it right.
It gets really annoying when you end up doing it,
Then when they come after you,
Act as if you have not done anything.
Worst of all, they paraphrase what you just did and try to make it look as if it's their own doing.
Just because you ain't the one doing it, it doesn't mean others can't get it right too.
