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.
If you need me, call me. I don't care if I'm sleeping, if I'm having my own problems or if I'm angry at you. If you need me and if you need to talk to me, I'll always be there for you. no matter how big or small your problem is, I'll be there.
