My eldest son got into a fight with a friend named Ryusei from the same class, and somehow either caused or didn't cause a minor injury... Since we couldn't just leave it alone, my wife and I went to Ryusei's house with a gift of sweets to apologize. However, the father who greeted us seemed extremely angry, exuding a sort of "monster parent" vibe, and kept making unreasonable demands, saying this isn't right and that isn't right...
