My dear writer, this was beautiful! What an intriguing, bittersweet story of coping with loss and missed opportunities. I felt a pang when I read that Minerva had never kissed Amelia (I fell in love with your zealous, bright-eyed, word-punctuating Amelia right away, so I could quite relate to Minerva's feelings about the missed opportunity). And the touches of lightness, so necessary in times of loss, were just right. The banter between Myrtle and Minerva, Griselda-of-the-monocle ...
Myrtle watched me, warming to her topic, clearly enjoying my evident shock. “I wouldn’t have said it was sex, not really, but Madam Hooch said it was, and she should know.” -- Yay Rolanda! And don't anyone let anyone say otherwise.
“A few years ago, when I caught her and Griselda Marchbanks in the prefects’ bath one night during exams,” Myrtle said. “She said Olive should have been more attentive to me.” -- Double chuckle -- at the fun, throwaway reference to Rolanda/Griselda and at Rolanda's insistence on mutualness.
A passion for justice lit up Amelia’s face when she spoke; her eyes widened, and her breath came more quickly, and her index finger would rise, punctuating her words. -- I cited this above, but it deserves a full mention.
