Say good-bye to your friends.

I'm leaving you tomorrow.

Before saying goodbye to their neighbors, the Smiths had to tie up some loose ends inside the house.

I got a farewell present from everyone.

Jane's farewell speech made us very sad.

I just dropped in to say goodbye.

I've come to say goodbye.

I think it's time for me to say goodbye.

I'm going to break up with Tom today because I can't take him anymore.

He didn't even say goodbye.

I haven't said goodbye yet.
