Thats the whole idea.

To properly address the topic, sometimes things doesnt require deep
thinking. Emotions, gut feelings, instincts, experience all play a
part when man and woman get in to a relationship, or even when it
comes to family and friends. If every thing requires logical,
thorough thinking, we cease to be human, and as the Bear says, we
become cold analytical machines. When man and woman made mistakes,
no big deal.
As for woman have eyes that cannot see, or for that matter human
have eyes that cannot see, remember the world is a Matrix.
We can see the keyboard, mouse and monitor in front of us because
we chose to, or is taught to see in such way. We believe in our
vision
We thought we can see thru our partner, friends and family
thoroughly, and believe they can be flawless or we think we know
their character and flaws, but things might pop up that might
surprise or shock us. Similarly, when faced with proofs that can
throw away all one's belief and thoughts away in an instant, some
of us refuse to accept.
That is the wonderful world we are living, Not good or bad, but
superbly interesting and intricate.
