Wave one's hand(s) v.s.wave hands

[Sin-Yu Tsai]

Can wave hands to sb means say goodbye to sb?
Or we have to add one's in the phrase?
Thanks.

 

[Raymott]

"Wave goodbye" is the term.
"She waved goodbye to him."

 

[Sin-Yu Tsai]

Thank you.
I waved hands to him.
I waved my hands to him.
Are the above the same?Does the term make sense without "my" if it means wave goodbye?

 

[Raymott]

No, the phrases you've given don't mean the same.
"I was drowning in the sea, so I waved my hands to the people on the shore." This doesn't mean you're waving goodbye (unless you actually plan to drown).

 

[Sin-Yu Tsai]

Thank you.
But I wonder whether waved hands to sb. can mean wave goodbye, too.
e.g. I waved hands to Mom and said goodbye.
Or I must say I waved My hands to Mom and said goodbye.
Is "My" necessary here?

You can say 'wave somebody off' to mean 'wave goodbye to somebody' according to http://www.oxfordlearnersdictionaries.com/definition/english/wave-off?q=wave+off
