There is a more delicate way to start reciprocity rules than to make something nice for just someone, so you can expect something to come back to. A form of this more subtle form of mutual relationship is the concept of mutual joke which the requestor reduces his initial request, the respondent may agree with the second request. Under mutual restrictions, we are bound to acknowledge a person who has given us a discount ie, if a person requests a big request to stop and you deny, you can agree to their smallest request, even though what you are suggesting Do not be interested in it.
