people think about things that they have to have as goals in life problems also things they have to solve and deal with .people also feel happiness sadness other felling based on whats going on .what it means is we all as humans in this world have to feel for each others and think about what we do we all must be together and not judge about if its a he or she or race or ethnicity and know we all are humans in this world to struggle and get through things and understand each other( know to be happy with who u are) basically that covers it up!:)
hope that helps!
