Ich werde eine coole Location finden, wahrscheinlich so ein Haus am See oder so, und dann lade ich echt alle seine Freunde und Familie ein. Und dann, das wird der Hammer, ich werde eine Band organisieren, die so seine ganze Lieblingsmusik spielt, weißt du? Und dann, weil ich ja keine Lust habe, selbst zu kochen, hol ich mir so einen professionellen Catering-Service, die dann für alle Gäste kochen. Na ja, ich hoff mal, dass das Wetter mitspielt und wir alle draußen feiern können. Ich sag dir, das wird echt ne unvergessliche Feier, und mein Freund wird ausflippen vor Überraschung, echt jetzt.'],

I'll spend many hours putting my thoughts on paper and bringing my characters to life. Well, I hope that readers also find my story fascinating; that would be really cool."],

Erst als ich in der Schule war und mich zum Mittagessen hinsetzte, bemerkte ich, dass ich zwei völlig unterschiedliche Schuhe anhatte! Ich hatte einen schwarzen und einen weißen Turnschuh an. Und ich mache keine Witze, die Leute haben es sofort bemerkt. Ein Typ namens Tommy hat mich Mismatch Mike genannt und bald haben alle mitgemacht. Oh Mann, ich war damals so peinlich berührt! Jetzt finde ich es einfach nur witzig und frage mich, wie mir das nicht aufgefallen ist. Das ist eine dieser Geschichten, die ich jetzt auf Partys erzähle, und die Leute finden es total lustig.'],

The energy was incredible, and I remember feeling so connected to everyone around me. It was as if the rain made the whole experience even more magical. I was surrounded by friends, and we all shared this special moment together. It was one of the best moments of my life, and I still get goosebumps when I think about it.
