I had a visitor one day. One of them stood on my window sill, looking inside. For a while we were staring at each other, he on the outside, I on the inside. When I stood up and approached the window, he flew away. I don’t know why I say it was a “he”. I just felt it that way.
The next day he came again, having another one with him. I had left something for him, outside. Soon, they became more and more, and now all these little fellows visit me almost every day.
