the computer mending man downloaded and installed Thunderbird as dh had a problem with Outlook Express. Then Thunderbird wanted the password when dh tried to send an e-mail and dh wouldn't type it in as "X has installed it and put all the passwords in so it shouldn't need it". So for 3 days he has been complaining that he can't send this (apparently very important) e-mail because he doesn't want to type in the password....
Today I lost it a little bit and said "The machine doesn't understand that it ought to know the password already, and I think you're being a bit silly to withhold the password just because it ought to know it. Just put the thing in when it asks for it and send the e-mail" (which he did - while I was out, mind).
