Poems about friendliness should not be too long. Six or seven sentences are enough. You can write them yourself.

Friendly flowers

Kindness is a ray of warm sunshine.

For strangers,

Kindness is a pair of selfless hands.

For those who have difficulties.

Friendly, like the bright sun.

To all who need to care and shine.

Friendly, what a beautiful word.

Friendly, warm language.
