A childhood belief about imaginary friends

When I was young, I had an imaginary friend named Margot(I would flip if you didn't pronounce it like Margo), and she lived downstairs because she was in a wheelchair until I "bought" her a rocket wheelchair that could fly her up to my room and she couldnt get out of her wheelchair, so I bought another one that reclined back because she got back problems from sleeping sitting up. Margot had a boyfriend whose name I forget. One day I blew up a balloon and drew a picture of Margot and her boyfriend. I then thought that if the balloon popped, then they'd die, so I kept it safe.

So they walked to the airport in my backyard (it was imaginary), and they said their goodbyes, got on the plane, and they never came back. :'( I thought they filled themselves with too much air and they popped
