Are you getting annoyed with a friend, but not sure how to let them know? Do yourself (and them) a favor and keep quiet about your frustrations. Just start spending more time with other people and either they will get the message or they'll initiate a conversation about why things have changed. Then and only then will they be ready to hear the truth you have to tell: without going into any great emotional upheaval. Not everyone is ready to hear the cold, hard truth about their behavior.
