A day for mirrors

Today, and November 11th annually, is "Mirror Day".  November 11th was chosen to be the day for mirrors due to the symmetry of 11/11 and also because when 11 is reflected in a mirror it still looks like 11. 

Mirrors are essential items in life. There are different types of mirrors, such as hand held mirrors, rear view mirrors, antique mirrors and so forth and so on. Moreover, they can be useful in various situations. For example, mirrors can be used when putting on make up or grooming or checking your physical condition, to check behind you in a car, or even to make a space appear larger or to brighten a room. 

The All Japan Mirror Federation established "Mirror Day" to reinforce the necessity and usefulness of mirrors.
