Escapee dog walks on air. Table Cape, Tasmania's North West Coast. February 2012. This Theme Thursday we are not talking about monkey's in rhinestone vests, we are talking BUBBLES. "BUBBLES?", you ask. Yes, BUBBLES. When I say BUBBLES I don't mean a thin, hemispherical film of liquid filled with air or gas (i.e. 'I'm forever blowing BUBBLES in the air"). Nor do I mean a globular body of air or gas formed within a liquid (i.e. 'fart in the bath'). No, when I think BUBBLES I think of something insubstantial , something groundless , something ephemeral . Not wanting to burst your BUBBLE S , but BUBBLES are usually impracticable illusions. That monkey you bought and stuck in nappies? It's never going to be human! That dog you saw floating in the air up at Table Cape? It was just rounding the crest!
