My Parents are going to adopt other kids, how do you deal with that?

There is no difference between two persons. You cannot judge or characterize people by where they come from. Their skins, hair and culture could be different but they all have a heart that needs love and needs to give love. Don't reject them, accept them in your heart with lots of love, they could be the greatest friends you'll ever have. Think of the fun you will have exchanging culture and ways of life. Why do you think people dream of traveling the world, they want to meet other cultures. You don't have to travel, you are so fortunate they are coming to you, so enjoy and be thankful to have them as brothers. God bless you
