Sherlock would deduce that....

1) I am back at work (as some of the pictures on the wall are qualifications, therefore I am probably in my study)

2) I like fast cars (Via Ferrari!)

3) I am lazy or perhaps like to think horizontally (how many people have a sofa next to their desk?)

4) My taste in artwork is somewhat eclectic (therefore I must have varied interests and tastes)

5) I can't be working that hard if I'm blipping!
