I would’ve gladly paid that yesterday. Scenario as described below:
Young boy arrives at shed to watch father removing tyre from rim.
Son: “Dad, are you okay? Your face has turned purple”
Father: [Wheezes] “Yes, son. All under control.”
Tools scattered everywhere, dishevelled appearance and tyre lever embedded in father’s forehead belie this, but son doesn’t press the issue. Times passes.
Son: “Dad, are you sure you’re alright? You’re sweating like anything!”
Father: [delirious]“All part of the process, see my perspiration is helping to lubricate the tyre off the rim. All part of the process...”
More time passes. Tyre eventually removed from rim. Once father has regained consciousness he inspects his work. As he suspected, valve has torn out of tube. No rimlock fitted.
Father: [thinks]” I’ll just grab the spare 18 tube I have. Had. Thought I had...”
There is no spare tube.
Father looks at ancient 19 inch wheel with rock-hard prehistoric tyre which he forgot to throw in skip. It’s holding air. Tries not to cry in front of son, as he brushes cobwebs from it and picks up tyre levers again.
Begins to repeat performance above.
