I used to have several invisible dogs, my first being an Irish Setter named Sinnomin--no, not 'Cinnamon'. Once I began horseback riding lessons, a number of invisible horses lived in my backyard. However, now I am left with Sinnomin, Dash the paint horse, a pack of wolves who visit occasionally, and the ever faithful Padfoot. (No, Padfoot is not Sirius Black, just named after him.) ...I am 14 years old, and still believe firmly in my invisible--not imaginary--friends.
