Person1: Oh !
Person2:What fools we were !
Person1: To think of it ! All my old silver ! It meant so much to me .
Person2:And my new car . To think that he simply drove off with everything in my car . That's what hurts me most .
Person1: What's so terrible too , is the fools we've made of ourselves .
Person2:I hardly dare call the police . They'll just laugh at us .
Person1: I'll never get over it . Oh , Harry , it was all so unnecessary . That man ! ! How could he do this to us after we'd put him up ?
Person2:And his story didn't even hold together . I feel such an idiot .

Person1: Who do I talk to if I want I to see some of them ?

Person1: In spring , people are feeling refreshed . They take off their heavy winter clothes and walk with a straight back and light steps . They feel they are full of spirits and energy .
Person2:Women in particular . They are anxious to get rid of those thick and clumsy winter suits and put on their new fashionable spring dress .
Person1: Well , when summer comes , the weather is hot and the leaves turn darkgreen ; the sun is blazing and the air is threatening . No one would like to stay in the open air for long .
Person2:That's true . In summer , the first place people want to go is a spacious room with air-conditioning or a quiet river or swimming pool .
Person1: I myself like very much to listen to the singing of some of the insects , especially the singing of cicadas .
Person2:In autumn , almost all fruits are ripe and all crops are waiting to be harvested .
Person1: And you can hear singing and laughing everywhere ! People are happy in autumn because autumn brings them harvest and richness and prosperity !
Person2:Well , winter is a season for relaxation , do you agree with me ?
Person1: Well , it's hard to say . For the fields and rivers , winter is a relaxing season , but for farmers , I think they might take a rest physically , but mentally they are still busy thinking , planning and calculating for the working of the next year .
Person2:Maybe you are right .
