As the train pulled away, he whispered, goodbye, and watched the platform shrink into the distance.

Her goodbye at the door was quiet but filled with emotion.

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

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.

She stood on the platform, goodbyeing each friend with a small wave before the train departed.

Many friends came to say goodbye when he left for college.

She kissed goodbye to the city as the plane lifted off.

She stood on the platform, kissing goodbye to him as the train pulled away.

At the end of every visit, he kisses goodbye to the old oak tree that shaded his childhood garden.
