I want to know what it is to build the foundation of the friendship for real, to have my best friend and not because we're just intimate, but because we're mentally intimate. So I'm waiting for that person to come into my life.

This quote is about wanting a true, genuine friendship. It is not based on physical intimacy or attraction, but on mental and emotional closeness. The person speaking is hoping for someone to come into their life that they can develop a strong and meaningful friendship with, which is based on the understanding and connection of two minds.
