Evan and Bonn, twin boys, celebrated their seventh birthday by rolling out the family album and dancing on it. PrunePit's new song was great fun and had a wonderful beat. Sock footed, their dancing caused random photographs to surface. Evan pushed Bonn off and jumped off himself. A photo had surfaced that puzzled him.

"Who's that?" he asked their mom who had been watching them play.

She stood and looked. "That must be your great-great-grandmother." She touched her ring and the picture floated up out of the roll and hovered in front of them.

Bonn asked, "Why is she wearing that funny hat?"

His mom appeared unsure. "That's what women used to wear back then, at Christmas time anyway. I think."

Evan said, "We learned about Christmas in school. And how houses used to burn wood for heat."

Bonn added, "And they thought reindeer could fly. And without wings!"

Their mom touched her ring and the photo fell back into the swirling mass of a million family media moments. "Christmas," she continued. "Used to be a Christian holiday. Can either of you tell me what a Christian was?"

Neither of them had an idea. Bonn spoke first, "Were they the ones that thought it was okay to eat animals?"

"Sort of," their mom didn't sound sure herself. "I think they ate Turkeys and Pigs as part of their celebration."

Bonn made a retching sound. "How could they?"

Evan added, "Our ancestors were evil."

"No," their mom said. "They were just ignorant. That's all." Then she brightened. "Hey! Do you two want to have your birthday dinner on the moon?"

Evan got so exited he tripped and fell onto the family album. A video of a dog, its mouth open, its eyes fierce, surfaced under Evan and appeared ready to swallow him.

The two boys just laughed at the video. Together they rolled up the family album and put it away. This, they felt, was going to be a great birthday, a birthday on the moon.
