Dear Chuck Our Son's friend thinks he has an invisible dog called "Bengo". He takes it to the pub with him and people even pat the invisible dog. We are very concerned that he has been working too hard recently. Can you help?

Chuck's reply

Dear Chick and Minky, Firstly I'm amazed at your names as one of my client's has similar names, spooky. As for your Son's "friend" I think we both know it is actually your Son we are discussing here. "Bengo" the invisible dog is infact a replacement for an imaginary friend. As a family you were probably too poor to afford one! Please don't worry, invisible dogs don't need feeding or walking and can be inexpensive as pets. Also there's no need to clear up an invisible mess either. I can give your Son the name of a decent shrink if you contact me privately. Dr.C.B. Brandon
