Light bulb
Location
Some days, the light is on.
It shines bright; rids me of the darkness;
Illuminates my surroundings.
Some days, the light bulb flickers.
It struggles to shine; giving off a weak and feeble glow;
Not necessarily dark, just very dim.
Most days, the light bulb goes out completely.
Refusing to shine; not a single flicker or attempt at illumination;
Making me become engulfed by the darkness, once again.
