Thank you for your concern.
What a pity we've lost such a great man!
Yes, indeed. 确实是这样。
I'm going to miss my grandpa. 我很怀念我的爷爷
I know how you feel.
My father is in the hospital now.
That's too bad. 太不幸了
Try not to get depressed. 别太消沉了
I can't help it. 我无法控制自己
It was terrible this time, wasn't it?
It sure was.
My mother died when I was ten.
I'm so sorry. 那太不幸了
What a shame.
I couldn't pass the test.
Never mind. 没关系/别太在意
