I am a mirror

If you look closely you will find I am a mirror

Then what am I as individual, and why are we different?

What is different are our aptitudes and our temperament, our thought and speech.
These in me, however, can be augmented by your presence.

How then is it that we are distinguishable?

We are different in appearance. Yes, this is true. We are physically different.

Is it therefore that our minds are physically different as well? Is this why we are different?

When you know what I am thinking is it because we think the same way or because you know me well.

Is this not a product of our environment?

The truth that is an object is individual.
Could it be that the secret of this truth is that it is universal?
