When we find people who seem to truly understand us, next we need to know their motives. What’s driving them in this relationship? Are they in it only for themselves and their interests, or do they care about ours as well? We trust people when we know that their motives are good, that they want good things for us, even if at times it might cost them. Good relationships are built on this bedrock of trust: I know that you want the best for me, so I trust you.
