It is rude but it is likely the right thing to do. Seriously. I would be happy to see Hilv with better grammar and spelling.
No, its really not the "Right thing to do". Dozens of people have told Hilv he needs to work on his grammar/spelling, you do NOT need to repeat that by making some statement about summer school. It is rude and uncalled for. Also, I don't think Hilv would want to work towards YOUR happiness. He should work towards his own, which in turn might make you happy, who knows.
Also, I highly suggest not retaliating against anything rude people say with something else rude, it makes you look bad.
When I said that I would be happy to see that. I did not mean that he should make me happy by improving his grammar and spelling.
