Well I'm human so I may make grammar mistakes, but for the main I try there is no " he done very good is I say." But comma or period missing from time to time. As for length...ha... its no one liners. Depending on if I'm allowed to create environments around me I may be able to go along for a bit. If restricted I could stretch it out some but it would he pretty bland. I would say on less then 5-6 sentences. Or little bit longer then what I am currently writing here.
