As if the sticky-keys dialog didn't cause people enough hassle already? I don't want EMTs dispatched to my house because my cat sat on my keyboard and didn't have the presence of mind to click the "Don't worry, I'm okay" dialog.
There is tape over my webcam. But shit, what if I just fell asleep on the thing? Would firefighters knock down my front door because I used my keyboard as a pillow?
