There may be a flaw in this plan.
I had considered clingfilm (plastic wrap) before, but early testing revealed a problem with the air supply. Also, I didn't want to run the risk of thinking of the band, Air Supply. (shudder) I thought about encasing myself in wood, but I knew that would only end in flames. Concrete seemed appealing, but there was that air thing again. Also, I kept hearing my contractor muttering something about sending me to sleep with the fishes. I don't even like fish. (They agree, by the way.)
That's why I have abandoned my aluminium death trap and I am now safely ensconced inside the belly of a large elephant. In case of an attack, there are a couple of exits. In addition, elephants are best known for their uncanny ability to hide. Ask any 6 year old.
Granted, it's a bit cramped in here and Clive (the elephant) doesn't seem too pleased with the arrangement. There could be a downside to this plan. I admit that it is possible that I haven't thought this whole thing through.
