In an American TV show, a man said at the hospital, "My insurance is balking at the bill." I didn't know the word "balk" so I looked it up the dictionary. アメリカのTV番組で、ある人が「私の保険はその請求をbalkしている」と言いました。 わたしは「balk」 という単語を知らなかったので、辞書で調べました。
It says that it is to refuse to do something. It also says it is used in baseball when someone stops in the middle of the action of throwing the ball to the player who is trying to hit it.
ふつうのオバサンです。よろしくね。 英語で何かするのが好き。読む書く話す聞く見る。人の考えを聞くのが好き。Talking with people all over the world is fun and you can learn something new from them, telling what you know to them as well. That's the reason I can't stop learning English.
