Ashibe-kun gets into a fight with Sugao-kun. He goes over to his house to apologize, but he isn't sure if Sugao-kun is even at home, so he sends Goma-chan in to check. So Goma-chan sneaks into the yard... only see a golf ball flying toward him! He dodges the ball, but knocks over the potted plants in the yard! Oh, no! Will Ashibe-kun and Sugao-kun ever make up?!
is because there's no sincerity 
whatsoever in a grown man's apology!
هو أنّ اعتذار الرّجل البالغ خالٍ من الصّدق
dass die Entschuldigung eines erwachsenen
Mannes nicht im Geringsten aufrichtig ist.
quand un homme s’excuse,
è che non c'è alcuna sincerità
nelle scuse di un uomo adulto!
é porque não há sinceridade nas
desculpas de um homem adulto!
это всё потому, что взрослые 
никогда не извиняются искренне.
