I've had two imaginary friends in my time. The first was called Bully, and was your standardised, everyone's got one, invisible friend. Were IKEA to sell imaginary friends then they would be like Bully, only called Boshtal or similar.
My second imaginary friend was not invisible, but rather microscopic. An antrhropomorphic representation of my immune system, I used to think he was responsible for killing germs and making me feel better. I remember one day comparing him to another friends microscopic friend, trying to determine which was the smallest.
