Nimble Deer in "What Brownie Wanted"

"Old Mr. Crow!" Brownie Beaver said.
"I might have known it," Nimble muttered.
"He has played a joke on you. It's true that I have a flag; but it's not the kind of flag you want. Some people call my tail a flag, on account of the way I wave it in the air when I'm startled. Of course you wouldn't care to have my tail on the top of your house." And Brownie Beaver admitted that he shouldn't. "But I can't help being disappointed," he confessed.
