Good friends will always be considerate for each other. They will be the shoulder to lean on when you are upset or troubled, and they will share in your joys and fun. Whether you are happy or sad, your good friends will be the first people that your subconscious thinks of. In many cases, you do not need words to communicate. Just a look will be more than enough for them to understand what you're thinking.
Ordinary friends are no more than acquaintances who greet each other with a nod. In your daily lives and ways of thinking, there will not be too many common grounds and you will not care about them as much.
