Come on give the lad a break, he’s new to it, a few years will have worn off the sharp edges, and he’ll be as cynical as the rest off us 
The fact that most off the replies seem to suggest that its not a hard job, just shows that you are all very competent, as you can do this without thinking, thus leaving your head clear to worry about tea, or when the next bit off skirt will drive past. 
Once after backing blind side in one go onto a bay, which just happened, I wasn’t trying to wear my pants on the outside off my trousers, I got asked by another driver to tell him how I did it(a newbie, whom I allowed to buy me a cuppa), but I just couldn’t tell him, I just do. I don’t feel like I’m spending lots off mental energy on driving, hence I’m not tired at the end off the day. Hence its an easy job 
But think to when you see someone who just cant grasp what it is to move a truck, some people don’t have the special awareness to see a route forwards or reverse and get on and do it, then they get flustered, then some ■■■ says today will do nicely(sorry I just cant help myself), and then you realise that the job isn’t brain surgery, but it does take a certain skill to do well, and that’s when it looks and feels easy, and it was shepherds pie 
Ps, I’m not have a dig at you Neil, but do your self a favour, get cynical quick, Remember only the muppets with a blue light matter more than you, and a BMW will polish out
