.... A random thought.

I wish more people understood:

most people in your life come and go. Most don't stay forever, because life changes... people change.
Some friends or lovers are forever (like soulmates), but most of the time people part ways.

It's a natural part of life and that's why you have to learn to take care of yourself. Be your own best friend and enjoy your own company... Realize you don't need anyone to give your life purpose.
