“Why aren’t you walking at your graduation?”
Mostly, I hate this question because people get angry and try and make me feel guilty about not walking. Usually, I can shut people up by saying either, “If I hadn’t told you, you would have had no idea that I wasn’t going to walk,” to the younger folks who haven’t yet graduated and, “Let’s be honest. If you could have skipped your graduation, would you still have gone?” to the older folks. The older folks usually hang their heads in misery and say, “Well, yeah. Graduation was no fun.” HAH! Right there! That’s your answer!
Like @ucme, it’s not so much the question itself as it is the tone that bothers me.
