So I was an Officer in a guild I was recently in (yes, it's a relevant information). I'm using a TipTac addon (it's an addon that makes your mouseover tooltip quite detailed and advanced, but the most important thing is that with a simple mouseover you can see target's guild, talents, mana, health, rank in his guild, etc ...). I have two computers (one is actually a work computer - a Mac - where I also have WoW installed), so one day I was running around in Dalaran on my Mage while playing on Mac (to clarify why this is relevant is that in Mac, the command to close an application is Cmd + Q). So I wanted to close WoW with the close command, but that command doesn't work inside WoW, so the game actually considered as if I used my Q bind, which is Mirror Image. So I wanted to close the game by clicking Esc -> Exit, and while doing so, I mouseovered a nicely geared Mage, so I thought I would inspect him with my mouseover tooltip for a second. I realised that that Mage is actually in my guild and is an Officer! Knowing everyone inside the guild by name, I became really curious of who that player is, then I saw my Mage's name -- when I wanted to close my WoW, I pressed Q and triggered Mirror Images, so I actually mouseovered my Mirror Image and wanted to inspect it. But wait! There's more! I use two accounts that I own, so what my brain did at that moment is think that I was playing on my other account and I mouseovered my Mage. I panicked, as I thought "****, someone hacked my account and logged my Mage" ... so I freaked out for a second, then it finally struck me that I was mouseovering my Mirror Image and what a brain-fart my brain just did.
