It was all about symbols.
When you went to his house everything was some sort of symbol. The paper bird in the cage a symbol of his attitude to pets. He’d say: “It’s the best bird I ever had. Never needs feeding, doesn’t shit in the cage, and its represents so many possibilities.”
He’d say: “Depending on the angle you view it you can see it could be about to take off, land, sing, the possibilities are endless and I like to think of them all.”
That’s where his reality ended sadly. It was like talking to a vacuum, there was endless possibility but no reality.
You could never draw him into any discussion about his real world. I think he found himself much like his paper bird. Stuck in a limbo from which he couldn’t extract himself and so it was ok to stay that way, after all he didn’t need to think beyond the possibility, did he?
