4, 4 me
The first thing that comes into my mind is the four seasons. I love the changes in the nature, I could not bear to live with eternal sunshine. I remember during my stay in northern Africa which in many ways were very interesting but the weather, so dry and hot. The dryness was the worst part. Everything was so dirty. I was actually longing for heavy rain and so were they of course too.
Here are the 'Four Seasons' in my little plot Tyra’s Garden.
First out is the winter
after spring comes summertime, then the livin' is easy... the Papaver is everywhere
FFFinally we are back to square one again, the long much to long winter.
Which season are you living for?
