How can you consider someone as your friend?

You could consider someone as your friend if they were there in times when you were happy and especially at times when you're sad. Sometimes other people only act as your friend because they want something from you. Some people are also there if you're happy and leave you when you're sad. That is not what a true friend is. Never trust anyone if you've just met him/her because sometimes you might be telling a secret to your own enemy.
