John didn't know what he had been expecting when he walked through the door of 221b but it certainly hadn't been this. After three weeks of no cases it was expected for the room to be a bombsite; but this...
When he was 'bored' Sherlock would often find apparently meaningless tasks to do, sometimes they were useful (like when he learnt to cook) but other times they were completely random and a waste of space.
Like this.
Walking into 221b John saw tiny rubber bands everywhere, in huge piles according to their colour and size. They filled the floor like rainbow sick and it was impossible to move without stepping on one. Huge plastic looms surrounded the man sitting cross legged in the centre of the room, who was huddled over his latest creation. Even the skull was heavily decorated with the colourful bands.
John wasn't sure whether to laugh or cry when he stepped forward and a huge mountain of rainbow bracelets toppled over, spewing all over the floor. Apart from the obvious question, 'where the hell did you manage to buy ten billion loom bands?' or 'why the hell did you buy ten billion loom bands?', John found himself muttering curses at the man before him.
Sherlock, to say the least, did not look himself. He was sitting in a hunched form. wearing a poncho (apparently made from loom bands- can you make a poncho out of loom bands? Apparently so...) and a crazy look in his eyes. He was making about ten bracelets a minute, chucking them onto the ground or putting them on his arm (which was covered in multicoloured bands). He then suddenly looked up with a rabid animal stare and shouted at John;
"I NEED A CASE, JOHN!"
John threw his arms in the air, spraying blue and pink bands everywhere, and shouted back;
"NO, SHERLOCK, YOU NEED A LIFE!"
