There are certain moments in life when saying Goodbye is too little to help those parting from each other get over this difficult moment. One might as well say: Look for the bump in the road! It makes just as much sense.
I have often heard people saying Goodbye, in different kinds of situations. I saw them waving their hands, faking a smile and walking without looking back. I have listened to them sobbing and twirling around to see if the one leaving has decided to stay.
In any case, the word Goodbye is far too hard to pronounce and impossible to deal with. Now it strikes me why Spanish people say Hasta luego!, which means See you later. It makes the parting moment more bearable, especially when the words uttered assure the other one that he/ she might see the other person soon.
