[Wassa matter, you don’t like watermelon? Think of the melon-divers who risk death and worse to bring you your mildly sugary, fridge-filling, instantly-rotting drink-in-a-rind! Think of their poor families wondering whether today might be the day that Daddy won’t come home because the shark got into the lagoon! Think of a closing square bracket!]
*beer, for instance**. Generally just the first one, but you have to be vigilant.
**and wine. Any amount.
