英语翻译
A ”favor" is doing something for another person that the doer has no obligation to do,For example,going to the store for a friend or mailing some letters so that a sick friend wouldn't have to go out in the rain.Since a favor involves doing something extra,it re-quires an expression of thanks.It is appropriate to thank the person again after the favor has been done.For a "bigger" favor,that is,one involving more time or effort,the beneficiary may also give a gift to the doer of the favor.For small things,such as holding open a door,a person simpiy says "Thanks".
