Also, if you were someone's friend, you shouldn't make fun of them nor hurt their feelings. People have feelings and they wouldn't like it if somebody just tortures them. So, being a friend to a person should not let them down and make them feel less comfortable.
Friends also trust each other and believe in them. And if they break your promises and tell other people what you say to your friend as a secret, then they're not trustworthy. It's better to choose a friend that will always be there for you and can be able to be trusted.
And finally, friends solve each other's problems by telling them how they feel and by even helping them to make things better. Especially by apologizing ; trying to change things to make it more better.
I hoped this thread will help people to understand what are true friends for
