For me, people who I like, I figure out kind of quickly. They are friendly and able to look you right in the eye. They give no pretense of wanting anything from me. They put you at ease. I told a story on here a long time ago about a guy I met who was good looking and friendly and we started a chat. I knew he wasn't liking me to date because a few minutes later he introduced me to his girlfriend, and she was really nice and friendly. You could tell that they were people that treated everyone the same.
