Being a stranger in a foreign land, I always hope to find a best friend who can be my support or someone to talk to when I need her. But in America, your friendships and relationships are always based on something material. The first thing a person considers when making friends is not the quality of the person, but other things besides that.
Whether it's friendship or love. There is always a balance in your heart to weigh what you pay against what you get. If the balance in the heart is out of balance, one party will be hurt. This is more likely to hurt people mentally than physically. Because only time can slowly heal the scars engraved in the heart over time.
