Read the poem and answer the question.

1 In a land of green and blue,

A lake so calm, a sky so true.

A child with grandpa by his side,

Adventure awaits, let's enjoy the ride.

5 Beneath the sun, so bright and gold,

Their fishing tale is about to unfold.

Grandpa smiles, a twinkle in his eye,

As they cast their lines, under the open sky.

Rippling water, a whispering breeze,

10 Nature's chorus, rustling through the trees.

Mountains stand tall, their shadows long,

A perfect place where memories belong.

Grandpa's fishing wisdom, patient and kind,

Teaching the little one, heart and mind.

15 The bobber bobs, a dance on the lake,

With each little splash, a new story takes.

Fishing poles in hand, sun on their face,

Time together, in this peaceful place.

Grandpa's laughter, a comforting sound,

20 Echoing joy, all around.

The child asks, somewhat fearfully,

"Are the fish afraid of the deep blue sea?"

Grandpa chuckles, a twinkle in his eye,

"No, it's their home, where they swim and fly."

25 The child, who wasn't sure about the deep blue sea,

Now loves fishing with Grandpa.

Their bond grows stronger, like the tide.

In this moment, side by side.
