Resignation

I bought a hot canned coffee, but it slipped out of my hand
and went deep under the vending machine ...

Another warmth ...

Resignation is sometimes important.

Belief

I often see “belief” in songs, but what is belief like?

It has become a difficult thing as time goes by,
but it is like you recognize the tea cup without confirmation
when you are said, “A tea cup is behind you.”

Comparison

Why does one compare oneself to others?

It might be because of competitive instinct.
Nature has its own purpose, but natural resources are limited.
So, nature preserves efficient species for its purpose.
This might be so-called natural selection.
The reason why we survive now would be in
that we are still useful to nature.
Nature might embed competitive instinct in us
to enhance the efficiency.

Perception

Thinking about the simplest economy consisting of only two people
who can't live alone, has to do something to the other,
which would make them happier,
to perceive various exchanges of words, services, goods, etc.
as "to be helpful to the other", or "to give and take"?
