Signaled hi or bye
Else clues• Acknowledged the crowd
• Fluttered in the wind
• Gave the hi sign?
• Gestured hello
• Gestured goodbye
• Greeted from a distance
• Greeted from across the street
• Greeted from afar
• Greeted wordlessly
• Marcelled
• Mimed goodbye
• Moved in the wind
• Said hello without words
• Said hi to the cameras
• Showed one's hand?
• Signaled goodbye
• Signaled hi or bye
• Signaled, in a way
• Signaled, perhaps
• Undulated
• Wished bon voyage, say
