Just because!
Once upon a sunny morning a man who sat in a breakfast nook looked up from his scrambled eggs to see a white unicorn with a golden horn quietly cropping the roses in the garden. The man went up to the bedroom where his wife was still asleep and woke her. “There’s a unicorn in the garden,” he said. “Eating roses.” She opened one unfriendly eye and looked at him.
“The unicorn is a mythical beast,” she said, and turned her back on him. The man walked slowly downstairs and out into the garden. The unicorn was still there; now he was browsing among the tulips. “Here, unicorn,” said the man, and he pulled up a lily and gave it to him. The unicorn ate it gravely. With a high heart, because there was a unicorn in his garden, the man went upstairs and roused his wife again. “The unicorn,” he said,”ate a lily.” His wife sat up in bed and looked at him coldly. “You are a booby,” she said, “and I am going to have you put in the booby-hatch.”
