Stella has 13-year-old identical twins. For a long time it was not easy to tell the boys apart. It was only recently that it became obvious from their appearance and the way they dress that although they look almost identical, their characters are very different. Stella is married to David and he is a scientist who fulfils all the stereotypes of scientists. On top of that, David is mildly autistic. If he hadn’t had Stella, he would probably have starved to death. When he is researching, he forgets the whole world around him and hunger as a feeling disappears by itself after a few hours.
