Rain on Diagon Alley
It was raining - hard. Diagon Alley was starting to flood and all of the customers had crowded into the shops, packed like sardines around the racks of goods. In Eyelops Harry was pressed against the cage of a disgruntled-looking eagle owl while next to him Ron was nearly inside an empty cage. Hermione, on the other hand, had cleared a little space around herself by piling her bags all around her; it didn't get her much but at least she could breathe without pressing against a stranger. Outside the rain fell, unconcerned by those people trapped inside, flooding the street with merry abandon.
