On their first valentine’s day together after they got married, Hermione sent Ron a howler. he didn’t realize what it was right away, and when he opened it was completely flabbergasted to hear his mother’s voice yelling at him. It was the same message he got when he stole the flying car. half way through the message, Hermione’s voice started to laugh and said “Mischief managed. I love you, Ronald.” The card then blew him a kiss, and exploded into mini heart shaped pieces.
