I read a quotation somewhere, saying: "We live in this world to feel at home." I would say: "We live in these worlds to feel home in all of them." Friends are always close to your home. Friends are essential. They stand up for you when they got to know you better. Usually, people with CLEAN mind have a lot of friends. It takes time until a new community gets to know and accepts you. First, personal prejudices and discrimination have to pass away. Thus, you can have many friends at different places.
