Been doing that for a while. Mostly because I'm curious but also people really love when you show interest in their thoughts with genuine curiosity. I started noticing this when I started asking more questions. It also became clear to be how few people do this to others. Then I started noticing that people I enjoy being around often ask me what I think or why. Most of us are so focused on what we think and want that I wonder why anyone would want to talk to us.
