Neighbour: "Do you have a pet possum now?"
Me: "Er, no. Have you seen one?"
Neighbour: "It's just that I heard you talking one evening to one when it was on your studio roof ... and then the other night I saw you following it when it walked along the top of your fence and across your clothesline and then it went under your house. You seemed quite conversational"
Me: "Ah, well, actually there are a number of them, have been a number of them, and I've been trying to catch them."
Neighbour: "Looked to me like you could have just grabbed them."
Me: "Er, well, yes... (thinks about lying and saying I am the possum-whisperer) ... er ... (thinks about explaining I have a blog and like to take pictures for it) ... (ends up just smiling lamely).
