[Facts] Re: And now for something completely diferent....
None of my imaginary childhood friends had specific names. They were just sort of general, supernatural "presences" that lingered in shadows and dark corners and to whom I might giving a knowing smile, thereby unnerving a particularly troublesome adult.
Some of my favorite "imaginary friend" movies:
Harvey
Drop Dead Fred
Bogus
Oh, and is Mike your younger son? :)
