This story provides so much support for my "Sherlock Holmes has ADHD" theory.
Does he keep all his letters stuck into the fireplace with a jack knife so they're visible and he doesn't forget about them? You just know if he puts those letters in a drawer he's never going to look at them ever again, they're just lost to the void. Or they'll wander into an "unlikely position."
Same with the tobacco in the slipper - "Put thing in strange but very visible place" is also a good tactic to stop things getting lost.
I love music. And people working together to create something beautiful. I I take a music class and I absolutely love how we are together and hold each other up. It dosnent matter if you have shit going on with someone when somthing happens and we are in class, we show up for eachother. Especially in marching band.
