What about "laughter"? In "laughter", the background of each person becomes very important. What is not funny to everyone else could be extremely funny to oneself, and vice versa.

In a conversation, although there is a smile on the face, one could actually be very irritated or sad. It is impossible for everyone to exactly have the same thought.

"Laughter" may exist in such a gap between values.

That is why through my work, I imagine and "smile" on everyone else. I wonder how they would look when I do so.
