Using proper grammar is like having sex with someone you love. To get the desired effectand really make your readers squealyou have to place the right words in the right places, finesse your commas in between the right clauses, and then interrobang the shit out of your sentences when youre ready to climax.
A bad grammarian is like a bad lover. For me, reading a poorly punctuated or ungrammatical story is like taking my clothes off and being touched the wrong way. I want so badly to be moved, to be rocked from the inside out, only to be slapped in the face by a dangling modifier or bored to sleep by a run-on sentence.
