I knew it was the other American from Michigan (which all the English teachers were pronouncing 'Mitch-i-gan' )
a roundabout is not quite like a junction. you only stop before the rou dab out if there are cars coming from the right. if the roundabout is clear, you should go. the who.e idea of a roundabout is to keep traffic moving.
I think your comment, Poppy, that independent schools just aren't that good here has helped me make sense of all of this. The actual systems are not that different between England and America, but I think independent schools here have more in common with American military schools than private schools (not all of them, we saw one that was cute, just way overpriced). A friend of ours once listened to me confess that I entertained fantasies of Aidan attending Eton on scholarship, and he said "I'm sorry to be the one to tell you this, but they wouldn't have him. The purpose of Eton is to take the Prince Harrys of the country and do the best they can with them." Noted!
