What are heavy? Sodden sea sand and sorrow.

What are  light?  1.25 kg weights and fireflies in a pitch black room in the middle of the night.

What are calm? The sea clipping the cliff edge and clouds floating in the gentle breeze.

What are rough? A stormy night at Brandon Country Park and elephant seals fighting over a mate.

What are lifeless? shells lying on a sandy beach and a person after death. 

What are energetic? Gizzy jumping in a lake on a hot day and a sprinter in the 100m.
