Oliver had been collecting food wastes from the great hall every since the last herbology lesson. He had a tin that he brought with him every time he went to eat and it had been slowly filling with things. Now that it was pretty much full, he figured that it would be a good time to bring it down to the garden and empty it into professor Myers' bin.

The tin contained a variety of food waste, including a banana peel, a tea bag, an apple core, an orange peel, and some coffee grounds. Most of them were fruits, apparently plants liked that. Happy eating, plants. Oliver dumped his tin into the bin. Well that was fun.
