The following quote is from the book Boundaries: When to Say Yes, How to Say No to Take Control of Your Life, by Dr. Henry Cloud & Dr. John Townsend:
"People like Derek ... can be lots of fun. Except when you pop their bubble about their unrealistic grandiosity and their irresponsibility. Then you become a 'wet blanket.' It's revealing to talk to the 'wet blanket' who is married to a practicing child. No job is more tiring."
