A tree.

A lone signal with many lights
Turning red for the rain,
Yellow for the sun,
And green for the summer hope.

A lone orphan, a lone parent,
Never seen its family
But takes after them
The seeds exploding.

A lone bark in a school
Freshly raucous in the rain,
Bright in the summer holidays
And tired in the winter exams.

A lone beggar, a free hugger
Arms always opened wide,
Leaves always a bowl
Smiling with drooping branches.

A lone house, a lone inn.
Birds land and fly, bats hang
The nests held by old hands,
Never hurt by a woodpecker.

A tree.
