When the OP in their faux naivete starts a thread to say they don't 'understand' something, when what they actually mean is 'I'm so clever and you're all doing it wrong'
They can't possibly 'understand' that people carry out tasks in a different manner to them and if they do, they're stupid because if they only did it the OP's way, i.e, the correct way, their lives would be sooooo much easier.
If they genuinely 'don't understand' that people do things differently, then I do worry about how they get themselves up in the morning.
If they want to start a thread about how great they are are something, then frame it in that way, rather than the 'I don't understand' angle, as it just makes them look as thick as mince.
