Reciprocity means to reciprocate. When you look for reciprocity quotes you will find that many countries exchange certain things in order to gain a mutual benefit. One example of reciprocity would be for the USA and Mexico to agree to accept citizens from the other country and to provide these immigrants with certain rights. Since both sides get the same benefits then the reciprocity enjoyed is mutually beneficial, and the privileges offered covers both groups of people. Sometimes businesses and other types of organizations engage in reciprocity as well, this is not something that is restricted to sovereign nations. Individuals can also enter into reciprocity agreements. One neighbor may mow the laws of both households while the other neighbor plants flowers for both residences. Both sides give something and get something in return.
