Do you ever find that some people seem to be from an entirely different planet to yourself?
Their planet isn't necessarily better or worse than your planet, just different.
For instance, my soon-to-be-ex-manager once asked our team, by email, for suggestions about how he could "Motivate and Inspire" us. Different planets entirely. If you're reading this then you're probably from my planet, but how, how, how can you explain to someone from this other strange planet that the first step would have been to NOT SEND OUT THE EMAIL?
Closer to the family tree, my Dad is a very practical, kind, down-to-earth farmer type. He recently got false teeth and I just happened to call him the day before he was to get the mold made. After he'd told me all about his cows he mentioned his imminent dentist visit and I advised him to take my Mum because "you usually make a better impression when she's around". My mum says he still hasn't got it even though she's explained it to him several times.
Actually I think he does get it but he just doesn't get why anyone would say it in the first place.
Different planets.
