There are ordinary people and there are tidy people. The ordinary person leaves his dirty slippers at the door, while the tidy person ensures that the slippers don't get dirty in the first place. The ordinary person uses a tissue to wipe his nose, while the tidy person holds a tissue by a tissue, which he then uses to wipe his nose. The ordinary person picks up a pen that he dropped and puts it back on the table; the tidy person picks up the pen and keeps it in exactly the same position it had been in before its fall. The ordinary person traces a horrible stink to the sock of his room-mate, and throws it out; the tidy person in addition to the sock, throws out the room-mate as well.
And finally, the ordinary person cannot possibly know the difference between being ordinarily clean and being tidy; whereas, the tidy person takes the pains to write an entire page on the differences between the two types, regardless of the fact that nobody is going to take the trouble to learn to be tidy, let alone read this...
