yeah, i've had small circle of close friends over the years, and usually I met them in college, we had similar views on things, similar personalities in some, not all cases, then sparked up discussion over lunch. Then later based on common interests such as watching movies or tv or books, we started to hang out more, get to know each other more, became more comfortable talking, shared aspects our lives, and built a deeper friendship. So, it's usually opening up and sharing something about yourself with them that makes them connect with you and feel more comfortable with you. And seeing whether that interest created more interest, connection, and committments.
