Evening. A nasty cold rain is pouring outside, drops are hitting the glass. A tall blond man is bent over the table and lies with his head resting on his hands. Just a few minutes ago he was writing something. There's still a lot of work to do - students' tests need to be checked, research needs to be done. However, William is terribly tired. The scarlet eyes closed by themselves, the lack of sleep made itself felt. It's ten o'clock in the evening - Sherlock will be back from work soon.
