I'm sure if you were to go back now the sky would be bluer than you have seen in a long time. I saw a very excited young man in India who for the very first time can see the mountains from his window and a lady saying as children they would lay on the ground with their father at night and look at the stars....said they had never done that with their own children as there was nothing to see. Coronavirus has taken much, but has also given some clean air to breath for the first time in their life.
