Hiya.
I'm 12, and when I was 4-10, I never had an imaginary friend. I didn't really understand how the other kids could see this freaky-deaky being that didn't move anything, eat, sleep, or take up room (like you could run through them). I also wonder if they were unrealistic (cartoonish) or more realistic.
But now, i have an imaginary friend who is a purple blob named NotBob. :]
