It's a fact that angels didn't need to sleep. It's also a fact that if they spent a significant amount of time on Earth around humans, say 100 years or so, they would pick up the habit. Balthazar had been on Earth since the Dark Ages and Gabriel had arrived not long after so they were both now in the habit of retiring at night and sleeping.
Out of all the angels, Balthazar and his older brother were the most knowledgeable of the humans. And human behavior came naturally to them now, so it was only natural that they would share the human's excitement on this date, July 20, 1969. Today was the day that man would finally set foot an a celestial body. Apollo 11 was due to land on the moon, and the Heavenly Brothers were going to watch the historic event on television.
Television was a sad excuse for the real thing but as Gabriel had pointed out, there was a good chance the moon itself would be overrun by angels and since neither of them wanted to be found by heaven, showing up on the moon would expose them to heaven's attention. The two had sat in the living room of Balthazar's Miami beach home and watched the landing. Afterwards they had speculated on what this development could lead to for humanity. After a while habit kicked in and Gabriel and Balthazar decided to turn in for the night.
That had been a couple of hours ago, Balthazar cracked his eyelid and looked at his bedside clock. 3 am and the most Dad awful rattling sound was shacking the windows in their frames threatening to shatter the panes. Then the rattling stopped to be replaced by what sounded like a high pitched whistle. When the whistling stopped the rattling started again.
"Bloody hell!" Balthazar said sitting up in the bed.
Tossing his legs over the side he got up and followed the noise to the guest bedroom. Easing the door open, Balthazar was treated to the sight of Gabriel sprawled on his back mouth open and snoring loud enough to wake the dead.
"Oh for Father's sake!" Balthazar said. "Gabriel! Turn over or close your mouth or something!" Balthazar gave his brother a poke in the side, Gabriel turned over on his stomach and the snoring stopped.
Balthazar turned back to his room with a relieved sigh. Climbing in his bed and snuggling down into a comfortable position, his closed his eyes. Only to have the snap open a couple of minutes later when another loud snore rattled through the house. With a loud huff, Balthazar conjured up a pair of ear plugs while mumbling about 'bloody snoring Archangels'.
The next morning found Gabriel in the kitchen snapping up a plate of Belgian waffles. "Hey Balth! I made breakfast!" Gabriel cheerfully greeted the grumpy Seraph.
"I take it you slept well." Balthazar grumbled.
"Like a fledgling." Gabriel agreed.
"Well at least one of us did. I on the other hand was up all night listening to a certain Archangel snoring loud enough to peel the paint off the walls." Balthazar went to the coffeepot and poured a cup.
"I do not snore!" Gabriel said defensively.
"No?" Balthazar snapped his fingers and a cassette recorder appeared on the table. Balthazar pushed the play button and loud snoring filled the room.
Gabriel was about to deny it when the snoring was interrupted by a voice mumbling the name 'Kali'. "Um, oops. Sorry." Gabriel said sheepishly.
"Do me a favor. Next time you visit, stay at a motel!" Balthazar said.
