Cheese..!

During the break, Lan sat herself next to a recumbent Potter who was diligently studying his pathology notes on the grass (grass!). Taking the opportunity to satisfy her perpetually rumbling tummy, Lan began to munch happily on her caesar salad, relishing the tranquil atmosphere.
Potter then raised his head (from sternal recumbency) and informed Lan that he could smell the cheese in her salad. He then went on to say that it smelled delicious and that he was jealous of her seemingly limitless supply of food before returning to his notes. What he didn't realise was that Lan could not smell this 'cheese' that he referred to. Hmm.
Some time later, Potter once again reemerged from his seclusion to once again reiterate that he could smell cheese and that it smelled sour and wonderful. It was then that he decided to get up and show Lan his eggplant snack. However, before he could even reach for his bag, both his and Lan's eyes were drawn down to these dark brown splodges on his cargo shorts.
"Oh" said Potter with dawning comprehension, "I think I know where the cheesy smell is coming from. This is dog poo."
Quick as a flash, Lan had jumped up from the grass and quickly inspected her posterior for similar stains before doubling over in laughter at Potter's misfortune. Potter was fortunate in that Lan had some serviettes handy which she offered to him out of the kindness in her heart (=D). Potter then had to scurry to the car and grab his (thick) overalls to use as makeshift shorts on that hot day. Poor guy LOL.

In the light of this event, Lan would like to make an amendment to her status as a grass appreciator-
Lan likes grass only in the absence of faecal contamination.
