Imagination deviation

A lot of kids have imaginary friends. I suppose it must be more common among only children or those whose siblings are distant in age. My brother and I were pretty close in age, but we had a slight problem in that he loved to compete over things. I didn't object to competing generally, but didn't like competing with him, since the only thing worse than a bad loser is a bad winner, and as a kid he was both. So we had imaginary enemies. Their names (and for the life of me I cannot remember why) were Doodoo and Mary, and we used to devise all sorts of games and feats of physical daring in which to battle them. We always won of course. I'm beginning to suspect we were slightly odd children.
