When I look at the top of the page and my inbox has a little glowing envelope?
I only ever really PM 2 people (who I knew before joining MN) and I've only ever had nice PMs from other posters.
So why when I see it light up, do I always get that funny little feeling?
You know like when the phone rings after 9pm or there's a knock at the door at an odd time of the day/night? 
Am I alone in this?
