I can clearly understand what Seeker is saying. I don't think those types of comments are unique to her town. I live in a big city with one grammar school. I've probably made those exact same comments to children I've known who have sat the exam. I've not made them to be patronising, it's just the kind of thing you say.
If somebody was to go in for a driving test and passes, you automatically congratulate them. If they fail, you make all the right noises, assure them you believe they will pass next time. You certainly don't call them a loser, nor would you dismiss it. Can you imagine if you only got one chance a the driving test. If you failed first time you were never given another chance to drive. Okay their might be others who decided they didn't want to drive, but you would always know that you were not good enough, or maybe you couldn't afford as many lessons.
Its bad enough here when the DCs get their letters for secondary school where most DCs are going to a variety of local comps/faith schools. Different schools will always be perceived as better than others and people will always believe that makes the people who go their better.
