Is This a sign of hope?

We had a 2 hour walk and avoided the rain but not the very very muddy footpaths. Came home and as I was filling up the bird feeders to my left the sun was shining,  to my right the sky was dark and threatening. Then a fabulous rainbow shone out of the gloom. I'm taking it as a sign of hope. I have to have something to keep me going in these trying covid times.
