@edgarblythe,
I would not use "replete" where you do ed. The word has a voluptuous sound. It creates onomatopoeic resonances along the preferred pathways. Especially for someone who has been conditioned in a certain manner. It is out of place in a scientific context.
I would have considered saying--"After I got the new one running, I thought it best to fit a new capacitor while I was at it, I hauled my tools and trash to the shop, where I found my new colleage had just arrived yawning and rubbing the sleep from his eyes. "You're not going to throw away that motor are you ed", he said,---and take it from there with a couple of pages of thrust and counter thrust on the subject of the fate of the motor and how a young man brought up in a throwaway society could possibly take a 'make do and mend' attitude to all this crap and you brought up in a 'cobble and patch' society and casually sling away a possibly serviceable motor.
How do you think it comes about that two blokes who have been exposed to an American socialization can have such diametrically opposed views on such an important subject? And surprising ones too.
Although your age might have made you cynical about these things and he still has youthful idealism.
