It isn't hers.

Amy's blue dress is wet.

You are too, too small.

Whose bag is it?

Mengmeng's car is new.

    A woman finds a seat on the train, but there's a bag on it. So she asks the man beside the seat, "Is it occupied（已占用的）?"

    "Yes, she will soon be back." the man answers.

    The woman is very tired. She sits down and says, I will sit a while till she comes back Ten minutes later the train starts.

    "Oh, the poor fellow. She loses the train, but she can't lose her bag." After these words, the woman throws the bag out of the window.

    "It's mine" the man shouts out. But it's too late.
