Two lights facing each other

I don't know why but here it is. "Koivu". A birch tree. That was in July back home. 

Now it's the season in northern Europe where two darks are facing each other. This is to refer to an old saying and I think it means the time of the year when it is dark during the day and dark during the night. It is the darkest season of the year in Finland. 

But this picture was taken in summer. When two lights were facing each other.
