It's been my experience that people who make proclamations about themselves are usually the opposite of what they claim to be. If someone is truly a loyal friend, then they wouldn't need to broadcast it; eventually, people will figure it out. I have a lot of good friends and not one of them has ever introduced themselves by saying, 'I'm a very good friend.'
