Arrrgh! My friend is living with a 35 year old guy who refuses to allow anyone to use the word "grown up" in his presence, to the point where he makes a BIG production out of it. He insists that he shouldn't have to grow up and plans to stay a child forever. I don't know how to tell him that there is a big difference between a childlike sense of wonder and just being an immature j*****s. He's insufferable.
