Friendship is learned by watching and listening to you. If she sees that your friends are people you like and trust and don’t pretend with—people who suit you—she probably won’t pick friends who just pass by, or people who can help her or improve her status. If you treat friends in a special way, if you are kinder, more generous, more sympathetic, more forgiving with friends, she probably will be, too.
