That is one of eight mosquito bites that I have right now.
I’m going to start going around biting mosquitos myself and see how much they like it.
UPDATE (June 02, 2010):
My mosquito bites are now turning into odd bruises…
If I’m infected with some random undiscovered disease that makes mosquito bites turn into bruises, and I disappear off the face of the planet within the next few days, it’s possible that this disease is fatal and that I died from it. If so, check in the chair in my office or in my bed for my body so it doesn’t start rotting.
