Two engineers, Rayella and Ray, were standing at the base of a flagpole, looking up.
A teenage student walked by and asked what they were doing.
We're supposed to find the height of the flagpole," said Rayella, "but we don't have a ladder."
The teenager took a wrench from her backpack, loosened a few bolts, and laid the pole down. Then she took a tape measure from her backpack, took a measurement, announced, "Eighteen feet, six inches," and walked away.
Ray shook his head and laughed. "Ain't that just like a teenager nowdays! We ask for the height and she gives us the length!"
