Barking Dogs Seldom Bite(people who threaten others usually do not hurt them)
Hi, Frank. What are you doing back in class today? I thought Mr.Tccker kicked you out yesterday for misbehaving.
He did. But you know that barking dogs seldom bite. I've had Mr.Tucker for other classes, so I know that he never stays angry for long. He has threatened to punish other students before, but he has seldom followed through. Actually, he's a very forgiving person.
So how did you get him to let you back in?
I went to his office after class and apologized for causing such a ruckus. I gave him my word that it would never happen again. sure enough, he accepted my apology, and here I am!
ruckus = 大騒ぎ
sure enough = 果たせるかな、案の定
