When you say goodbye it means that you will be parted, and that you will not see the person for some time. Goodbye means farewell, and the separation may be very short, very long, or for any time in between. When you say final goodbyes this is typically done at a funeral after the person has passed away. Saying goodbye can be a source of incredible sadness because you will miss the person and will not see them again soon.
A man never knows how to say goodbye a woman never knows when to say it
