Random

It is all pretty much random.

We all remember different situations,

Different moments of time,

Different faces, different places.

Your mind chooses a random assortment of thoughts, feelings, emotions and memories.

Every brain has its unique way to think,

and it is at random of how your brain will process.

There is no way to tell what will be seen after your blink. 

There is no way to tell what is waiting in line. 

Who knows; It is all random.
