I looked through a telescope yesterday again, also to show my neighbor the Jupiter and its five moons. At the end three neighbors joined me and were astonished at what they saw. I promised them another lesson about the night sky soon. It is somehow strange to learn that some people don't know that our Sun is a star and have no idea how to find the North Star in the sky. I took all this for granted from as long as I can remember. Obviously I had better teachers or maybe I was just more curious.
Anyway, I was happy to share my knowledge with my neighbors. At the moment this seems the only good reason to be in this world - to share what I know.
