When I was about 3 - 3 and a half, I believed that Mickey Mouse, Donald Duck, Goofy and Alice from Alice in Wonderland lived in the lady's house down the road. Whenever we visited I never saw them and was CONVINCED, WITHOUT a DOUBT, that she was hiding them behind a closed door that I was never allowed in.
