Cloud is a visible mass of water droplets or frozen crystals suspended in the atmosphere above the Earth's surface or the surface of another planet. Pillows are a buffer head, usually used to sleep on the bed, or to support the body on the sofa or chair. Crying is a physical response as a result of reflex or of emotions felt by someone. Who will win?

On Earth substance usually water vapor precipitation. With the help of hygroscopic particles such as dust and salt air from the ocean, small water droplets formed at low altitude and ice crystals at high altitude where the air is cooled so saturated by local or larger convective lifting non-convective scale.
In some problems, high clouds may be partly made up of supercooled water droplets. Droplets and crystals typically a diameter of about 0.01 mm (0.00039 in). The most common of solar heating during the day of the air at the surface level, the lift frontal forcing warmer air masses will rise up and orographic lifting of air over the mountain. As the air rises, it expands so that the pressure is reduced.
This process expends energy that causes cold air. When surrounded by billions of other droplets or crystals they become visible as a cloud. In the absence of condensation nuclei, the air becomes saturated and cloud formation is inhibited. in a dense cloud of reflection shows high (70% to 95%) throughout the cloud visible range of wavelengths, so that it looks white, above.

At first the pillow shows the level of welfare of one's owner. The pillows have been known by the ancient Egyptian society. Then pillows with modern tailoring techniques and pillows with ornaments known in China as a high value goods which later also known in medieval Europe. In Tudor England, pillow widely used; previously believed that only women who will give birth to have it. The Industrial Revolution was a witness of the large-scale production of textiles and pillows as decoration. Chinese traditional pillow often made of hard cases are derived from wood, stone, metal, or ceramic instead of stuffed with cloth. Some of the ancient Egyptians also sleep with a pillow of stone.

| Crying |
The reaction did not cry easily fabricated or falsified because when crying tears produced someone obscures vision and cripple his ability to attack or defend and send a signal to those people closest that a person is in a state in need of help, appeased, or accompanied.
- Communicate with other humans, from the point of view of human evolution, crying is a reaction to another human communication capabilities close to him and increase the chances of a person's survival. In one study revealed that the tears are complementary sadness. In this study, two photos are used, a photograph is a photograph of people cry with tears, and other photo is the cry, but the tears removed using digital techniques, people who saw the photo states that the person who photographed look more sad, whereas if the tears deleted digital, people who see much wrong and revealed expression photographed person puzzling.
- Mechanisms to release emotional stress, another theory states that crying is a mechanism of the body to relieve stress. Because the tear reflex and emotional tears have a different composition of the compound, where the reflex tears contain more water (H2O) while emotional tears contain more protein ACTH which are linked to one's level of stress. This theory argues that crying helps the person to get this protein out of his body, but the research on this is still limited, unfinished and could not be concluded.
