Anyone else bad at mind reading?

I had one of those "Am I supposed to be a mind reader?" moments today.

Last week I was told the materials for a science summer camp class I was teaching would be prepared, so I didn't think anything more of it. Today I asked where the materials were, only to be met with a response that made it seem like I should have known there weren't any. When in fact there was...

That got me wondering... how do you not lose your rag with them?

At my school, it often feels like the emphasis is on making the in-house workbooks look polished and presentable, while basic management and communication fall by the wayside. I don't mind adapting when plans change, but I do mind being expected to know about changes that nobody tells me.

How do you deal with this? Do you check on everything multiple times just in case, or is this just something you've learned to live with? For me personally, I am at the point already of just counting down the months with this hagwon already. For personal reasons, I can't just leave.
