How can you tell what another person values?

When I meet someone new, I often ask them what they’re reading. I get a lot of information this way. I get information about likes and dislikes. I can follow up with a myriad of questions that tell me a lot about what a person values.

If they’re reading nothing and follow up questions reveal they’re unlikely to read anything in the near future, I gain the most knowledge.

When visiting a new home or place of business, you can assess the pictures on the walls for clues about values.

Do you have ways of telling what another person values?

Please, enlighten us.
