Some time ago I noticed that Microsoft Outlook recognizes calendar invitations received via email and, before being accepted or declined, automatically adds these entries to my calendar.  When I first experienced this, I thought it was a bit odd and accepted it as a feature.

The other day I called a large company that maintains my personal and credit card information (along with that of about five million other Americans) and learned that the customer service agent could help me login to my account by telling me the password that I had previously set. Surprised, I asked "You can see my password?", to which she replied "I can see everything!"! (I know that these exclamation marks look silly, but they really did occur on both ends.)
