I just read a post on this blog about the first day of fall / autumn.
My comment was this:
I could not have said it nicer or better.
You are right, the fall (autumn in Europe :-)) is a beautiful season. I think what I like are the cobwebs and the cold air in the morning. Everything seems to be much slower, more peaceful. As if the world goes to sleep for a few months.
On the other hand, when the sun comes out, things are getting warmer and nicer and the vibrant colours let you enjoy nature in a very special way.
What a lovely time!
