For whatever reason, at some point in my childhood, I used to have conversations into a walkie talkie with no one. I never had an actual imaginary friend, I don't think. I had a very close set of friends (Frisbee, the bear; Ben, the bear; Joel, the Cabbage Patch Kid), but none of them imaginary. And I'm almost positive I wasn't talking to any of them on my walkie talkie, either. Just someone out there.
Of course, no one real or imaginary ever responded either.
Why?
Because I didn't have a walkie talkie.
I used to have conversations into a travel-size Head and Shoulders Shampoo bottle and pretend it was a walkie talkie.
Where other children had imaginary friends, I had imaginary toys.
Over and out.
