“I personally do not care. Good day, sir.”

You should care about grammar and punctuation. They aid in communication and everyone wants to be understood clearly, no? Sorry if I came off too harsh. My last line was intended to be an expression of exasperation about how common poor grammar is in general, not specifically directed at you. Anyway, I hope I haven’t put you off learning. I know us grammar Nazis can be annoying, but we mean well.
