First, let's talk about the word "Aloha", shall we? Does it mean "hello" or "goodbye"? It can mean both! Traditionally in the Hawaiian language it can even mean affection, peace, compassion and mercy-- that's a lot of love all rolled up into one word. Additionally, Hawaii is often referred to as the "Aloha state", perhaps to capture the loving feeling which the aloha spirit, if you will, represents.
So, if we use Aloha in its form where as a goodbye send off, then tonight was the beginning of these type of "Aloha farewells" before the Hawaii departure.
