Sherlock and you had a small family, just both of you and your daughter Rosie that you take care of together. One day, they had too investigate a crime scene and like always, they needed the two of you but you couldn't leave Rosie anywhere and you didn't want to take her to the crime scene, she was a baby anyway, but Sherlock didn't care if she went with both of you, so there you were, having to go there in 10 minutes and discussing what to do with Rosie

Of course, you didn't had enough time so even if you weren't convinced about it you took Rosie with you, Sherlock seemed comfortable in the taxi, just looking at the window seeing London in a pure state of spring, but he noticed your look and he decided to talk in his usual stoic and kinda cold tone
