Probably part of some larger conspiracy. I bet she's bugged!
I'm working on a currency trading project at the moment so quite often have some very sensitive info on my screens when I'm working from home.
I read a forum post on another forum about a currency trader (who I know online) who had a heart attack at home and had some money stolen by a family friend whilst the friend "looked up directions to the ER" on his as yet not locked PC. The forum post was pitched to warn you that you sometimes can't even trust friends and family.
I spent the next five minutes or so reviewing my own security procedures and listing out who has physical access to my PCs and laptops etc when my eyes met with Fabric's and what I can only describe as an intense stare off ensued.
I swear the bastard is selling secrets to fraudsters. He spends the whole day sitting on my hands staring at my screens.
