A Stupid Note

There was a stupid note posted in my building this week.  Perhaps not stupid.  More like painfully obvious.  Here's the gist of the note...

Heat in our building is regulated by radiators.
5 is the maximum heat setting.
Don't regulate the heat in your flat by opening the window. 

I think that I was more annoyed that there was this big notice posted in Czech.  Thinking that it must be something important, I made an effort to figure out what it said and then became disappointed that it wasn't something more substantial.

So maybe it wasn't a stupid note.  Perhaps it was just annoyingly disappointing.
