What do you think is their relationship? Do you think they are romantic couples? The answer is NO, they are just friends who keep each other happy and treasure each others company. We don't need to label someone greater than a friend in order for him or her to make us happy. We just need to appreciate the simple things they do, since small things make large difference, and these difference will not be removed from your heart even you and your friends are not together. Let us treasure our friends and appreciate what they do and tell them that they are all what we need to be happy.
