So what if there are spelling errors - I have a friend that graduated with an engineering degree inventing machines for optometry, went back to UofM med school and can't differentiate 'your' and 'you're', among other things. Though I can be a spelling and grammar nazi, I'm not going to dog on someone with an education far better than mine. I'd be more concerned about teachers that can't spell.
That being said, I'm glad this model is being honest. More power to her "dumb" ass.
