A fifth grader looked downcast, so her teacher asked. “What’s the problem Carol? I hope it’s not homework again. “
“Well, uh, yes, it is, “replied Carol “I was stupid and made my homework paper into a paper airplane. “
“Carol, you’re right, that wasn’t a very bright thing to do, “said the teacher, “but this once I’ll let you just unfold the paper and hand it in. “
“Oh, but that won’t work, “said Carol, looking even sadder. “You see, the plane was hijacked. “
