F this, F that - drivers and swearing

When I was a kid, I never heard my Dad swear. If he was doing some job around the house and things weren’t working out, the worst I ever heard was maybe “The ■■■■ thing won’t fit,” or similar. I just assumed that my Dad never swore. As I got a bit older, I would “help” him when he was fixing the car in the garage in the garage and the odd “Bloody” would creep into his speech. In my mind I just accepted that being in the garage was “bloke time” and so the language had become more “blokey”. As a teenager and between employment, he got me a job at the small (only half a dozen employees) engineering factory where he worked. I was mortified to hear that pretty much every single sentence he uttered while at work contained the F-word. I don’t think I ever saw him in the same light again.
