When my son was little, he had an imaginary friend. His name was Dubi-dub. They were inseparable. We were all courteous of him, he'd only been sat on a couple times that we know of! But then we stopped hearing Jeffrey talk about or to him. It seemed he was gone and we all missed our friend.
A couple days ago, Jeff and I were alone in the car and I heard him talking. I thought he was talking to me but when I asked him to speak up he said I'm talking to Dubi-Dub.
Welcome back old friend!
