Fog in the city

Some say fogs are droplets of water suspended in the atmosphere ..
Others sAy it is an atmosphere in which visibility is reduced because of a presence of a cloud of substance.

Minsk in the fog is not ordinary. Cold fog clears the smog of the city. It's nice to breathe deeply. But in winter the fog is very cold. Therefore, it's nice to finish the night walk in a warm house with a mug of warm tea.
