My mother is more like myself. She likes to go shopping in the colonies. Sometimes, we go together, but only when the rover is available or when one of her friends come by to pick us up. Martians are conservative about what they buy, because livable space is limited. Typically, one goes shopping with a bag of things they no longer want or need and returns with the same bag filled with new things.
Most stores accept items for recycling or resale.
Processed materials are valuable here. Anyway, I would have spent the day exploring Europa but my mother kept interrupting me about Diogenes. It's been this way ever since the weekend. I went out to the garden to get away from her using the excuse that I wanted to see how the automatic garden maintenance systems was functioning. Of course she knows I'm trying to get away from her.
