Duties of a lighthouse keeper

There was a storm last night
Blew away wrong and right
Watching the waves crash down
.

Now our words like boats
Either they sink or float
Are they designed like that
Can't they come back

Last night I was a lighthouse
Only needing to keep you there
Like a lonesome shadow searching
Like a sea fog in the air
I'll keep you there

Called on my radio
Frequency dipped below
Audible levels
So I sat in my wet clothes

Keeping the wicks trimmed and lit
After the storm had hit
I turned on my light
But it couldn't find you
