父の病状は一喜一憂です。 My father's condition seems to improve one moment, but the next moment he sinks again. 表面的な物事に一喜一憂する人が人を管理する立場につくべきではない。 Somebody who wavers between hope and fear over superficial things should not be appointed to a management position. 彼は試合の結果に一喜一憂している。 He is now glad, now sad at the progress of the game. ボスの顔色に一喜一憂の毎日。こんな仕事やってられないよ。 I can't keep this up. It's an emotional roller coaster around here and all we have to do is look at the boss's face to know whether everybody is going to be happy or sad. 彼は一喜一憂した。 He fluctuated between hope and despair.
