No offence taken.
We tradies are very tolerant of the foibles of engineers ;-)
Sometimes we even allow them to be our friends despite their inadequacies, what with all their book-learnin’ and shoe-wearin’ and big words and that making them difficult to understand.
Though sometimes a tradie will get a head injury and suddenly be able to do serious mathematics and physics and stuff and go on to get a degree, but those folk can never really be trusted what with them having a foot in each bucket so to speak.
