I had a whole host of imaginary friends as a child - mostly TV characters, often from Neighbours. I also had an imaginary dog (the golden labrador Bouncer from the Oz soap opera "Neighbours") who I would walk when my grandparents were taking me somewhere.
The embarrassment they suffered when I used to hang back and announce that we had to wait because Bouncer was peeing.
