How some boys honed their swearing
They built model airplanes.
You see, a lot can go wrong in that process.
Propeller blades can snap.
Landing gear can come out of the box inexplicably malformed.
An errant drop of glue can turn the plane's supposedly clear canopy into a gooey blob.
I'm sure some boys suffered these setbacks in silence.
Others, however, gave voice to their frustration with choice selections from some recently acquired vocabulary.
No need to name names.
