Can you hear me that when it rains and shines, it’s just a state of mind?

The season of rain has started again. Grey skies, raindrops against the window, but inside it's warm and with a cat at your side and some music of  The Beatles, everything is perfectly fine. I try to practice this state of mind every day, and as a real summer-person this is some task for me. I like to live outside as much as possible, and when the colder times start again, I always feel a bit melancholic.
