I think one of the worst things a believer can do in a relationship with another is to try to determine what someone is thinking, especially if you think they are upset with you.. many times a person will be a thousand miles away with their thoughts and troubles.. Another is to take someone else's word for something they supposedly said or did.. Don't ever take someone's word alone on something to make a judgement about a person.. it's notoriously unreliable and very often incorrect..
