Friends are special people, they stay with you through thick or thin and they enjoy spending time in your company. Some individuals may act like friends but then betray you as soon as your back is turned, or pretend to like you just to gain some advantage or benefit from you, and this type of friend is not true and should be avoided at all cost.
True friendship is seen through the heart, not through the eyes
A friend knows the song in my heart and sings it to me when my memory fails
True friendship comes when the silence between two people is comfortable
