Adopted people are classified as those who are not loved by anyone or anything in the world. In essence, they are not real. If you are friends with an adopted person, do not stop being friends with them, simply do not treat them with normal human respect. However, they should not be confused with retarded people because they are normally able to produce normal thought functions. I am going to stop there because its not cool to make fun of retarded people. Retarded people have something mentally wrong with them, thus concluding that their situation was not their fault!
