Sherlock seemed to ingore those comments. He didn't seem to realise she was flirting to annoy him. He was focused on other things. Mainly to do with the case. He wasn't going to even pay attention to flirting, he wasn't even sure what it was.
He knew that being normal was overrated. Well at least it was to him. He found normal people downright dull.

"Shut up, I don't want to hear how good it is." The detective was getting sharp with her. He was feeling a bit miserable from hunger. He knew that he needed to get away from her before he could get any food.
His stomach was growling badly, He closed his eyes. He knew that he was going to loose it. 
The detective was struggling to handle his hunger even more than normal now. He knew it was getting close to goint to long without food.

"I didn't ask for a Nanny." Sherlock snapped. He knew that he didn't need one. He was doing ok without looking after himself. He was looking at her. The detective huffed and he walked still. He knew John would make him regret it.

"Yeah she is having a day off, she normally does today." Sherlock replied. He looked at her "I think she is." he didn't seem to bother with Molly's private life all that much. He was thinking.
The detective continued to walk by her. Sherlock was feeling tired, he was not letting that win either. He knew since his accident he had been exhuasted easily. He knew he was still healing.
