What is interesting is that communication is at the heart of many things unless you are alone — and many are completely unaware of this. E.g. driving your car in traffic is quite definitly communication, as others have to “read” your behaviour and interpret it. Good drivers are very concious about what they communicate in which situation, bad drivers communicate completely without knowing about it and are bad at reading others communication.

I think you should always think a little bit for the person opposite: Did you give enough context? Is it ambiguos? etc.
