A check

Which of these tells you that a question has stopped being a question and started being a feeder?

It is about something seriousIt makes you feel anxiousYou have already had a clear answer and you are asking again for the reliefSomebody told you it was silly
Yes

Feeders are defined by what they do rather than by what they are about. A question you have already had answered, asked again to get the feeling down rather than to learn something, is doing a different job from the first asking, however reasonable it sounds out loud. Getting a ruling once is exactly what you should do.
