It's not in Sherlock's nature to be awkward...well it is, but not in this way. Now, how could he play this cool?
Luckily he didn't have to think too much before Sherlock and Joan's phones rang simultaneously. He picked up to Gregson and her to Bell only to be told of a case. They had to be down at the station within the hour, and so both went their separate ways.
Sherlock went and jumped in his shower which seemed pretty dangerous at this point considering his current predicament. He started thinking about his feelings for Joan, which was always risky. The water cascading down his shoulders really calmed him and let his thoughts overcome him. However, he knew it wasn't the right time.
Quickly flicking the temperature from hot to cold, he finished off his shower and went to get ready for the day ahead. Going to his wardrobe, he looked for something to wear. He didn't know why, usually the first thing that fell out of his wardrobe would be the first thing he there on, but today he really thought about it. Eventually he chose a fairly smart shirt, a cute sweater and his best fitting trousers. With a quick comb of his hair and a check in the mirror, he was ready.
Reaching the front door to put his shoes on, he heard the familiar click of Joan's heels heading towards the staircase. She cascaded elegantly down the stairs, leaving Sherlock gobsmacked. He had to be careful he didn't make this too obvious and looked down to continue tying his shoe, only making tiny glances towards where she was standing. She stood there in one of her more casual dresses, long, slender legs protruding from just above the knee and sleeves just capping below her shoulder. The beautiful, green material half clung to her gorgeous figure and around her neck draped a small silver chain which accentuated her collar bones. On her feet were some killer black heels which ravelled up around her ankles. Sherlock looked at her in appreciation and utter admiration. She gave him a small smile before stating that "you look nice, who's the lucky lady?" with a slight chuckle in her throat. She walked past him and headed towards the door. He was gobsmacked, it took him all of his power to not turn around and say "you".
Today was going to be difficult considering he could barely keep his eyes off her.
