They picked me on.

（いじめられたよ。）
　「オペラ座の怪人(The phantom of the Opera)」ブロードウェイキャストでファントム役の人のインタビュー（NHK教育）より。彼は小さい頃太っていて、周りにいじめられたそう。だから、周囲に受け入れられなかったファントムの気持ちが分かる気がするんだ、と言っていた。

• "pick on"＝「（からかい）いじめる」という意味。私の辞書には「（人の）あら探しをする、小言をいう」と載っていた。これも以前とりあげた、人に被害を及ぼす時の"on"だね。（参考：04/5/5
  • Why don't you pick on someone else for a change?←嫌な例文だなコレ・・・
• ちなみに「太っていた」というのは "I was chunky." と言っていた。chunky は口語で「ずんぐりした、(布等)厚い、(ジャムなど)塊の入った」。女の子が「ぽっちゃりとした」という時は plump が使われるみたい。
  • She's a little plump.
  • The nurse was a cheerful plump woman.
  • The baby's nice and plump.
