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.
I would rather walk with a friend in the dark, than alone in the light.
It's far better to be unhappy alone than unhappy with someone so far.
Things change. And friends leave. Life doesn't stop for anybody.
Real difficulties can be overcome; it is only the imaginary ones that are unconquerable.
