A mouse may not attack you in your sleep, but it may bite you.
An optical computer mouse uses a light-emitting diode and photodiodes to detect movement relative to a surface, unlike a mechanical mouse which has a ball which rotates orthogonal shafts which drive chopper wheels for distance measurement.
The earliest optical mice detected movement on pre-printed mousepad surfaces, whereas the modern optical mouse works on most opaque surfaces; it is usually unable to detect movement on specular surfaces like glass, although some advanced models can function even on clear glass. Laser diodes are also used for better resolution and precision. Battery powered, wireless optical mice flash the LED intermittently to save power, and only glow steadily when movement is detected.
A fancy mouse (“fancy” means “hobby” in this context) is a domesticated form of the house mouse (Mus musculus), bred to be used as a pet. Fancy mice are also called feeder mice when they are sold to be fed to other animals usually other pets. Fancy mice have also been specially bred for exhibiting, with shows being held internationally. Mice enjoy living together in groups so that they need suitable housing with nesting areas provided.
Fancy mice is a term to describe mice that have been selectively bred for exhibition. They can vary greatly in size, from small pet mice that are approximately 15–17.5 cm (6–7 in) long from nose to the tip of the tail, to show mice that measure 30 cm (12 in) nose to tail. Pet mice weigh about 29–44 g (1.0–1.6 oz) but large show mice can weigh up to 130 g (4.6 oz)]citation needed[.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
