There is a similarity between time and emotion.
A person’s emotion is very unstable; a person could be very devastated but a consolation from a friend would make him very positive. however, right after a friend leaves, this person could be depressed again.
Time goes by. it always moves forward. a second hand of a clock does never stay where it wants to be.
I combined these two ideas and created an artwork.
Overlapping means the unstableness of an emotion.
