The battery is needed, not the bulb.
Coz the bulb doesnt need another bulb to light.
The cactus needs just few drops of water, not a tank of it.
For the cactus will die of too much to drink.
The surfer can only surf on tides, not on a tsunami.
Or it will drown him.
And the sailor needs a calm breeze, blowing his sail to his destination.
And he'll pray and pray and hope for the typhoon and the storm would get past the ship so that his precious cargo wont find the seabed a comfy home.
