I miss having free wifi, and being surrounded by all my books and clutter. I also miss Sherlock, I worry too much about him but he's my baby.
And the not so secret, secret stash of chocolate that I have in my room.
Whenever I've been away for work or when I went to the many school camps, what I missed most is all of my routines. Being organised and doing everything at the same time, for the same time, in the same place every single day relaxes me and keeps my brain from freaking out too much.
I miss home so much that I don't like going away unless I have to.
