Sherlock had always put ignored his feelings, compassion was useless, it didn't do anything and most of the time no one got anything useful out of it, only a broken and empty heart. But when Sherlock started experience feelings towards John he didn't know what to do. I mean John was straight and it would ruin their friendship if Sherlock told him about them. So Sherlock decided he would forget about them, and it worked for a while, that is exactly two months and seven days before Sherlock was reminded, quite suddenly, of what it was he had forgotten and left behind.
John stepped out of his bedroom, half dressed, ready to go for a shower. He had had another breakup with a girl the night before and needed a nice long shower to comfort him. He didn't know what he always did wrong, he had had so many breakups that he couldn't remember all the reasons, but most of them tied back to Sherlock. It was always down the lines of the women thinking he was gay, which he was not, or that he cared about Sherlock more than them and that they spent way to much time together.
After his shower, John had quickly ran downstairs in only his towel wrapped loosely around his waist, to try and find his shaver.
'Sherlock, where is my shaver. Have you seen it?' It was then, when Sherlock turned round that all of his hidden feelings had been brought back. John was standing there, towel only just holding up around his waist, his torso was still shiny and Sherlock could see John defined muscles in his stomach. Johns hair was darker and contrasted against his tanned skin and the stubble outlining the edge of his face, only made him look more masculine and definitely more seductive.
'Um, no i don't think I have seen it, sorry John.' But Sherlock knew exactly where it was, he had seen it lying around on the kitchen top, in the way of one of his experiments, so he had binned it. And anyway Sherlock liked John looking like this.
'Oh okay then, I guess I'll keep looking then.' And with that John ran back upstairs.
