The Sky is Grey, Heavy With Dark Clouds

The sky is grey, heavy with dark clouds, that's not a metaphor - autumn is here colder, darker and more miserable, more than that. 

 

They change the clocks so it's darker earlier. The only light we see now is out the office window. 

It's wake, work, dark. Dark like chocolate, dark like coffee, dark like secrets. 

They are similies and in a way metaphors too.
