Last night, I found an urgent message from my boss in my inbox, saying the file that I'd been working on all day Thursday and that he needed done by the end of it wasn't in the attachment to the e-mail I'd sent him saying "Ta-daaaa!", and could I try sending it him from home?
Which is when I found out I couldn't as I can't remember what password I used when I set up my wi-fi 16 months ago. I've had to go to Burger King and make use of their free wi-fi there. But what if my laptop gives up the ghost and I need to hook another one up to my own wi-fi at home?
