Doodling in Physics

I am a pond
all it takes is a touch
and I ripple and shimmer.
I am the grass
all it takes is a breeze
and I nod in agreement.
I am a cloud

all it takes is a little water
and I'm gloomy with disappointment.

I am the wind

all it takes is some cold

and I run terrified.

I am a shadow

all it takes is some light

and I trail and follow.
I am the moon

all it takes is a rock

and I am riddled with holes.

I am the stars

all it takes is a mist

and my glow is dimmer.

I am a flame

all it takes is some water

and I sputter and drown.

I am a heart

all it takes is a little love

and I am happy.

I am a smile

all it takes is a kind word

and I widen with joy.
