Tend to look back; and in the blink of an eye, everything has changed so much, positively and negatively...

How people who are once acquaintances can be friends, and how people who are once good friends can being acquaintances.
Nobody holds any responsibility in this however. Fate has it.

A change of surroundings, and people drift apart.

Don't know why, but just feel so lost without them.

Move on...
