Happy, if you are going to post deliberately 'outrageous' things, how are you expecting people to react?
You and I were pretty much arguing the same point on the other education thread yesterday, so I for one was in agreement with you.
I'm not going to go back and try to work out which of your posts were genuine and which were just you trying to get a cheap thrill out of winding people up, but frankly, I think that's a wierd thing to do on the Internet. We can't see each other to be able to work out a posters meaning, we can only go from words on a screen. Most of us don't know each other, so personally I find it better to take each post at face value.
When you post asking a question that could easily be perfectly genuine, then later say you were joking, I think that's rude. I accused you of having no manners because I believed that you were asking about something you didn't know, I answered, as did others, then you chose to only thank one person for making the effort for trying to inform you. How are Randoms on the Internet supposed to know that you were joking and live in Kent so do know the difference between the different types of school? I didn't know the difference when I first had children, my only personal experience of school had been private with friends at comps, and I'm sure there are plenty of people that don't know the different types of school because they have no need to know.
Whether you are genuinely well mannered or not, your more recent posts really haven't shown good manners.
