Am I a bad person?

Well, OK, but I mean for this in particular: Like any decent and civilized person, when I find that someone has left their email logged in on a public computer, I close it for them. First, however, I send them a politely worded missive from their own account pointing out that they should get into the habit of closing their email, so as to not get snarky self-addressed emails (Or worse things, like deleted inboxes or having someone send obscene messages to their moms). It has occurred to me, however, that some of them might not take this to heart. Maybe if I started "deleting" their mail by putting it into a folder labeled "Oh noes! They be erasin my emailz!" they'd get the hint? Or would that be too mean?

Heh. That reminds me of a funny Army story. In a SCIF, you're not supposed to ever leave yourself logged into an unattended computer without at least locking the screen saver first. Failing to do so would lead to stern lectures on the importance of proper handling of classified materials, and/or many pushups. Some NCOs, though (not me, heaven forbid) would engage in more creative chastisements. For example, taking a screen shot of the desktop, setting that .gif as the wallpaper, and then moving all the desktop icons to a folder labeled "I am an idiot who should learn to log out properly" hidden somewhere on the hard drive, which would still be accessible from the start menu. Then try to avoid laughing out loud when the hapless individual couldn't figure out why they couldn't open anything. Ah, those were the days... :-)
