As the new year began, I sent a message to my friend saying 'Happy New Year'.

This painting has a beautiful contrast of light and dark.

The Acheron river is located in Greece.

He said 'Open Sesame' as if by magic, and the door opened.

When dawn breaks, the birds start singing.

There are many beautiful acacia trees in this park.

The period of time before daybreak is quiet and beautiful.

He was in love with her subconsciously.

The subconscious has a big impact on our behavior.

He was unconsciously humming the tune.
