For now. you're not thinking about leaving Luna. You have a good job. working as a tour guide for visitors from Earth. Some days. like today. there are no visitors.so you have the whole day off.
As you leave the tour office. you step out under the wide lunar Dome. the sun is shining. but when you look outside the thick glass windows. everything is black. white. and gray. Outside the dome. Luna is a dusty. rocky desert.
"What are you doing?"
You turn around and see your good friend. Taman.
"Nothing. I was just thinking about how living on Luna makes us colonists different from Earthlings.
