your father, Sherlock, was too busy with his work, always doing job trips or always writing papers and you started thinking that he doesnt love you. A night, you cant sleep, and you walks to your father's office, there, you see that he is watching a old picture of you, your mother and him, he has some tears in the eyes but when he see you he wipes they fast and say

"Ah...honey...whats happend?"
