In the slightest, it was impossible to assume that the mother knew, Philip never mentioned it, but it is true that he never showed much interest in girls.

Maybe his mother just knew what they were saying, mothers always know, but maybe she saw him sometimes, or she got to her to go to a gay club. Sometimes, when he was in the mood and time. But Oliver and I came together a couple of months ago, when they both entered the university–the same faculty, just another department. Even half a year ago, it would not have occurred to him that he would be in their rustic kitchen to represent the smiling mother of his friend, let alone that he would also be his young father.
