my sister had one named jenna. it used to move with the family from house to house to house. my sister's sorority little's name was jenna. when she called the house for the first time and my mom answered the phone, she was a bit freaked out b/c for a split second she thought it was the imaginary friend.
I had 4 imaginary friends and they were the Ghostbusters because that's been my fave movie ever since I can remember. (Yes, my friends, I am a crap movie freak!)
I did--- his name was DayDay. Not sure where the name came from. But DayDay did everything with me and went everywhere. We moved when I was 5 years old--DayDay stayed behind at the old place.
I have a cute story abotu my best friend. When her and her sisters were little, her dad made up an imaginary friend for them named Jimmy. Her father passed away in October. She's getting a new puppy tomorrow and she decided to name it Jimmy, in honor of her father!
