Rhubarb Protection

There's a fly in the kitchen. The hugest most gigantic fly of all time. It's barely afraid when I walk towards it.

And there's uncovered food. So what do I, saviour of all pies do? I cover the cake. And the rhubarb pie, which my mum made this morning and which I'm not sure if it's supposed to be covered yet is sitting in front of me so that I can keep a watchful eye on it.
And I'm sitting by the window, which is my awesome plan. The fly likes rhubarbs, I can tell. Sooner or later it will sucuumb to needing the pie, and then it will be fooled and will fly out the window.

This fly chose the wrong kitchen.
