This was before Christmas and sometime in the fall...but I had to explain to my mom (who is actually a programmer, but in the COBOL days) how to start an Apple account.
As you well know, an AppleID consists of your email. But I spent more than 10 minutes explaining to her how her Apple password was NOT her Hotmail password, as she was using her hotmail ID for her AppleID.
Funny enough, a few weeks later, I was teaching a web course and showing students how to start a site from scratch off of Amazon S3. One of the students didn't have an Amazon account and had the exact same problem: trying to use her email account password to log back into Amazon
