For most of my childhood I never went to school, so I have similar troubles with these things. Especially when I was younger in public schools(only for like 3.5 years total from k-12) for short times I would have no idea what to do when teachers asked things. I remember teachers passing out things and being like "Why did they hand me so many copies?" and I didn't realize I had to hand them backwards. Or they'd be like "Hand out these papers" and I'd know nobodies names. Awkward times...
At college it's a lot better, but there are problems; At the community college I go to, most of the teachers simply have people blurt out questions/comments during the lecture when the teacher pauses for a breath. It's weird, I write down my questions and can never find a time that seems right. Which sometimes never comes... I like the hand holding up a lot better.
What's worse is when you're the only one who wants to answer, or can, a question. It's always "An acid base reaction always forms a...?...?...? crickets..." me "A salt and water." after nobody else wants to pipe up. I don't want to be "that guy" but it drives me crazy.
