I’m not the authority on the written form of English, but COME ON, MAN… “Should of?” It’s should’ve for goodness sakes!!!!!!!!!!!!!!!!!!!
I’ve noticed a lot of people eliminate the words “to be” in some sentences. For example, “Your car needs washed.” I can forgive this grammatical transgression in conversation. But, when you’re writing for a news outlet, this is simply unacceptable.
