If the name fits, then fine.

But if it doesn't, then what more can you really do?

As for me?

I named my sadness after I realized I've have it for so long I might as well name it.

So I named it "Hello."

No wonder I'm so bad at starting conversations. 

I realized my happiness comes and goes so often that I might as well just say...

Goodbye.

And the name sticks.
At least until someone comes up to me with a "Hello" of their own. 

And I will only say "Goodbye" when I know they're happy without my "Hello".
