It's the Most Idiotic Time of the Year

We have have a small tree in our front yard that we hang ornaments for Christmas. The tree is getting bigger, obviously, so my wife got some more ornaments for it. No problem so far.

When I got home from work one day, she asked whether I could not put those up on the tree as well.

"Not right now.", I said.

"Why not?", she asked indignantly. She immediately assumes any refusal of work on my part is due to laziness.

"Because it's dark out.", I replied.

"So?", still indignant.

"I. Can't. See. The. Branches.", I said.

"Oh."
