Poor little boy, I don’t bloody care - spell-proof and grammar-proof the bloody thing dammit. “Its” for possessive, “it’s” for pronoun+verb; “por que” if question, “porque” if answer; “apposto” if annexed, “a posto” if it’s OK.

This is a good sentiment for general writing.

(also, at least on-line, if you notice later that you messed up, then fix it!)
