It's the reason I never ask questions in tutorials (even though that's part of their purpose), and generally never ask anyone for help because what if it's something easy and I'm just being stupid and they'll agree and think I have no brain and then hate me and-
Right, but even if you think the question shows you as stupid, at least one other person in your tutor group is probably pleased you asked so they didn't have to -- think of it as a public service :-D
