One of the wonders of the modern age is the personal computer, and close behind is the spread of information on the internet, some of it actually useful.
I can easily confess to being ignorant as to how to write programming code and being able to solve the many riddles that come up while doing so. I am certain the techies all have their quirks, and I also believe these quirks are often expressed in the programs they write for the Great Unwashed to use.
One example I encounter on a daily basis, whether on my home pc or the one I used back in the day when I was gainfully employed, was the ever-popular Delete box for e-mails. We have all seen it, and have dumped untold thousands of e-mails into the Delete box regularly. I am certain you have seen the quirk as well: next to the Delete box is quite often a number in bold parenthesis, purporting at first glance to show the number of e-mails you have in said Delete box. Here is where the quirk comes in; that bold number actually shows the number of unread e-mails in the Delete box, not the total number of e-mails residing therein. I cannot fathom why it matters to someone, whether me or a programmer, how many unread e-mails are presently in that file. I know they are unread, because they are 99.999% spam or junk e-mails that I put in there myself, precisely because they were unwanted. I also am unsure why it would matter how many I have in there, read or unread.
I can only think a computer nerd did it simply because he is a computer nerd, and needs to get out more into the real world.
