I recently posted the following 'trick question' which met a lot of mixed reception (twelve up votes and twelve down votes)
Now I don't want to delete the question, due to the time people have spent on it anyway, and in favour of the accepted answer.
I have edited the question multiple times in favour in the accepted answer, however users are still proposing other answers that are not in the spirit of the puzzle. I consider this to be quite a waste of time, since they are no longer good answers, but rather just the reiteration of other answers.
Anyway, this brings me to a broader point:
Is there a reason why I cannot close my own question, and rather can only vote and have to wait?
