Well, four, if you count 'off',
The switch is a small knob for two fingers,
Turn 'til it clicks 'senough,
The knob is on the round, chrome, raised, flat base,
Stem tapered to socket,
The bulb's incandescent, surprising me,
California's like so green, isn't it?
The shade's simple, black trim top and bottom,
Hard for it to contrast,
Not quite a wallflower, 'cause it's not shy,
With the light that it casts,
It brightens me,
At least on my one side,
On th'other, I'm aware it's no effect,
As if it can't reach what I want to hide.
