When my younger brother was in the first year of junior high school student and studied English very hard. After his English class, he said “僕はグラマーの先生が嫌いだ。I don’t like a teacher who teaches English grammar. ”
My father said “グラマーな先生なんて、素敵じゃないか! Why ? She might be wonderful, since she is glamour.”
In Japanese language, both grammar and glamour have same pronunciation in Katakana ”グラマー”
My brother did not understand what he was said. I think he was too young. “Hm? Not she. HE ! The teacher is a man !!!”
My father said “OK…a man?…Not nice…Yeah, you are right…”
My mother and I laughed at their funny conversation loudly.
