"Well," I tried to explain, "one uses passwords to log into accounts. Each account can have only one password but if you have different accounts, each one of them can have a different password - and this is, indeed, preferable. For instance, I have e-mail accounts at Yahoo, Google, my work, and a bunch of other places, and each uses a different password."
"I didn't understand half of what you said," was the reply, "but I have only one e-mail - hotmail."
"Well, then," I reasonably reacted, "you should have only one password for it. Can you show me what the problem is, instead of trying to explain it?".

She's shopping regularly at some local store. She used to have some discount card for it while her husband was alive but after he died, the shop switched to a different, web-based system of coupons, and she never figured out how to use it. They kept pestering her about "how much she would have saved", so she decided to finally try it.
