Goodby, old friend; may your journeys bring you joy.

At the old harbor, sailors exchanged a wistful goodby before the ship set sail.

She kept all his handwritten goodbys in a small box under her bed.

After the long visit, she goodbyed everyone at the station with a heavy heart.

At the airport, he kept goodbying his classmates with awkward waves.

Goodby arrived at the gallery opening with a sketchbook under his arm.

She bent down to kiss goodbye before boarding the train.

The train platform echoed with hurried goodbyes as families hugged one last time.

At the train station, she goodbyes every traveler with a small wave.

To 'goodbye' someone politely, you should smile and wave.
