A(-), you're Adorable

I never even saw the vicious, beastly, bloodsucking insects that on Saturday decided that a hefty serving of blood group A Neg was exactly what they needed to get themselves through the day. And why they chose the backs of my knees (delightful though they are, as I'm sure you'll agree) for their feast I don't know, but I now have swellings about the size of my fist at the back of both legs, which makes walking or sitting down very uncomfortable. They both itch and hurt, which is a curious sensation.

Oh, and one had a chomp at my foot as well.
