How is the weather?

We often start talking about weather when it seems like we have nothing to talk about at all.But could this apparent daily topic of conversation refer to a complex interconnection of codes and metaphors between human beings in social interactions ? Can one experience insecurity, fear, hope, joy or sadness through reflecting on weather? Can it reflect our individual perspectives and visions towards the world?
Starting conversation about the weather is considered normal and safe everywhere, whereas talking about politics can be highly unsafe in some countries.
The restriction of smalltalk to weather can thus be a barometer of individual and political freedom.
