There is no substitute for for good face to face (even on the phone) talk.
Talk = trust, and talk = shared experience. If you have a conversation with someone you now have a shared experience. Your perspective might not be exactly the same, and you may disagree, but you were both there.
Same goes with teams. The more we can face head on the things we do, want to do or be, with clarity and concern for each other the more the caring and shared experience grows.
