Hello everyone,

Could you please tell me the meaning of "waved" in the following text?

I was going to leave for London the next morning. I imagined walking through the village to the coach in my new, smart clothes. I am sorry to say that I was ashamed of Biddy and Joe, and so I tols them that I wanted to there alone.

When the morning came, I said goodbye to Mrs Joe ans left the house. I waved to Biddy and Joe, who were both crying, and then turned and proudly walked away.
