so little time.

When it comes to departures. We tend to say something out of sincerity when you're leaving.



See ya later is the best choice, because it says that you intend to see them again sometime in the near future.



Good bye means you are not intending to see them anymore, so you're making your ending moment with them pleasant in the aspect of saying, "I'm glad I met you."

And finally.



Farewell.



Farewell is you won't see them again, so you wish them the best.



I like that.


Farewell.
