Why carry a flashlight? Because a natural event each day is called "night" -- it's dark.


Exactly, and even if it was day time, there are places that are dark even during the day.

Also, the unexpected can happen.
Lights are not guranteed to be there at all times.

Last week I was working late in office when power went out. Thanks I had my little trusty LED flashlight to find my way around and shut things down before leaving the building.

I wonder why many ppl find this as hard to understand as rocket science. Unexpected things (or emergencies) can and do happen.
