No, nor could mine Flickety. Having said that, my son has had to learn huge amounts about the more arcane reaches of English grammar for his job and my daughter has had to learn to write accurately and under pressure for a website that reaches a massive international audience. They came out of school and university with good skills, but they know far more now, because their careers require it.
At one point in my career I had to learn to write reports where every sentence contained a judgement (and a critical reader would throw it straight back if it didn't). It took a huge amount of time and effort to get that right.
Everyone needs to learn the basics properly, but how we advance from that depends on the career path we take, doesn't it?
I don't particularly like reading texts that have poor punctuation and grammar either, but I get equally irritated by posts that are perfectly written, but contain no original thought or insight based on the poster's own experience or understanding.
Writing is about communication isn't it?
