Who gets the last piece?

Well, the birthday girl of course. This year my birthday cake was a flourless chocolate cake, recipe from the Scharffen Berger baking bar insert. Recipe asked for 62%, but I only had 70% on hand and that is what I used. The cake is very rich, not very sweet, and at the same time has a light feel in the mouth because of the whipped egg whites. I really enjoy this cake, which means a lot to me since I don't like eating cake all that much. Did I just write that? Oops, I should be ashamed of myself being a cake-lady and all.
