If some one uses bad grammar, it may not be their fault, maybe they went to a bad school, maybe they moved to an English speaking country after they had grown up speaking a different language. If you decide you are not fond of others grammar maybe you could buy them hooked on phonics, or tutor them in your free time

Edit: Go ahead and Neg me for this humorous comment, I honestly do not care and it would just prove that who ever is neg repping me has no sense of humor.
