Why?! Why do some people not realize they sound so uneducated when the post things.. It's basic English.... I've read so many post today that I mentally correct their sentence... Using "do" instead of "does" or "is" instead of "are" I'm like holy moly why why why?! I know you are old enough to have taken an English class in school! Someone had to have verbally corrected you at some point of your life?!?! Ebonics from any race just gets on my last nerve. Ok rant over, I'm going to bed now. Goodnight all you beautiful mommies💕
