Whose mistake
〜としたことが ・ 〜ともあろう者が ・ 〜嫌いがある ・ 〜ではあるまいか ・ 〜たことにする
In this lesson, you will learn to blame yourself for a slip you would never normally make with 〜としたことが, to say someone of a certain standing should have known better with 〜ともあろう 人が, to admit a bad habit with 〜嫌いが ある, to put forward a careful suspicion with 〜ではあるまいか, and to talk about treating something as if it had or had not happened with 〜たことにする and 〜たことになる. Back from Seattle, Mori holds a meeting to look at what went wrong.
By the end you will be able to say
