Angela is always having fiendish ideas that get Charlie into trouble. Like the time they hijack the milkman's float, and lock Miss Bridge in the gym shed, and when Angela pretends to kidnap a baby. But in the end Charlie gets her own back with a vengeance.
Angela is Charlie's best friend, or best fiend as Charlie accidentally wrote in her essay. But fiend is probably a better word, as it's Angela who puts a spider in Miss Menzies' sandwich, and plasters glue all over Laurence Parker's chair... Angela has a knack of getting Charlie into heaps of trouble but friend or fiend, life is never dull for Charlie when Angela is around!
