Mine was Misty...but I had been reading Misty of Chincoteague when I got my bike. I also would tie rope to the handle bars like it was a bridle...it only took two spills to figure out that did not work well.
I used to do that same thing!!!
Never fell though. Loved it.
I used to make horses out of wrapping paper tubes as well.
As for imaginary friends, I had them all the time.
Most often I would assign that role to a stuffed animal but for the most part, everything in my life had a personality.
The toilet was a person and in order to take care of it, you had to feed it.
The door required lots of air, so it needed to be opened regularly.
The fridge would tell me it was cold so I would open it to let in some warm air.
The washing machine would drown because it would drink so much water. Many times I had to save its life by pulling out wet clothes and dumping the water into the toilet.
Our fans would get tired and need to be scratched so I would have to granb a straw, or a butter knife and stick it inside of its little holes to scratch its back. It would vibrate with pleasure.
Our car was a girl, and trucks and bigger cars were boys
They all needed to be rubbed with towels and have sheets put over them so that they could sleep while they rested after running down the street.
Our car though... well.. she was really classy.
While driving down the street she would lift up her tire to avoid potholes and other things that could wear on her and make her look ugly.
She was always given enough space to park in and other cars would watch her. Even people. Though they would wave at my mom a lot because they too realized that our car was classy.
