In a concession to the tearable punster in me, I offer you the following recommended greeting for those going through the text-message phase:  Are “u” in morning?

It’s so much better than “What’s good about it?”  (though not better than Gandalf’s disquistion on the goodness of mornings!)

And it might put some of us in mind of a bit of ancient wisdom with a divine stamp of approval:

It is better to go to the house of mourning
    than to go to the house of feasting;
for this is the end of all men,
    and the living will lay it to heart.

(source: Ecclesiastes 7:2-8 RSVCE)

Despite which, I do love feasting.  Fortunately, in its proper season, so does God!
