Serenity.
On the day after the birth of his son who wasn't really his son, Joseph the carpenter watched the sun come up over the little town of Bethlehem. It had been a hellish last couple of days, what with the nose-to-tail census of Quirinius traffic-jam on the Nazareth-Bethlehem donkey-way, and then the cock-up with the booking at The Inn. Then, on top of the whole giving birth thing, suddenly every man and his camel was dropping in to say g'day to the boy. Nightmare.
But here, in the stillness of the early-morning, Joseph felt calm, at peace. The wise men had stopped talking and were snoring gently in their corner of the stable; the shepherds had finally gone back to their flocks; even the bloody cattle had quit their incessant lowing. Mary and the boy were asleep; the boy who had not cried once the whole time. Joseph's guess was that this inner serenity came with the territory of being the Son of God.
It had been a heck of a night, what with the actual birth and then all these complete strangers coming over to adore the boy. That some of them brought presents was nice. The gold might have been a tad too much, but the myrrh was lovely. Joseph wasn't a big fan of frankincense because, for some reason, he associated the word with big hulking monsters, but the thought was what counted. He also wasn't a fan of the pale, bland, giant chicken thing that the innkeeper's wife had cooked for them to celebrate his son's birth. Joseph couldn't see this catching on in the future.
Of course not everything had gone smoothly. When the wise men dropped into the conversation that they were meant to tell Herod where to find the boy, so that he could kill him, that was an awkward moment. Mary had not reacted well to this news and, even after they assured her that now that they'd seen the young fella no way were they doing this, she still wanted them to take their gifts and hook off. It had taken her ages to calm down, but the weirdest thing, for Joseph, was that through all the shouting and the flinging of myrrh, the little boy, no crying he made.
