I watch how people treat those with less power, like their waiters and waitresses.
I watch how people talk about others.
I watch if the person respects my time.
A good sense of humor. This is just a personal preference. My humor is pretty deadpan and I don't want to constantly worry about accidental offense.
Patience. I look for patience.
Attitude towards nature. This is just a personal worldview thing. I like people who feel comfortable in nature.
A sense of awe and curiosity about the world.
There are more. These are it for now.
