Murphy´s law

The sun shines to the back wall of my bed/livingroom for one week now and also at the beginning of December for another week (if it is not cloudy). It stays on the well about 6 minutes.
I have an idea for photo, that I would like to carry out now, before its too late.
Today everything was ready, but then a friend of mine called. He calls me one - two times at year, and now was the moment. He had very important message to me and it took over 10 minutes for him to tell it.
So, the moment was over, but tomorrow is another day.
It has been, so far, the only telephone call, I´ve had today.
On the wall is portrait of me, painted by my late uncle in 1962.
