Sorry for the appalling set, I just needed to make something so I could give an update.
In Maths, the people who normally sit between me and Sam were absent, so our view over to each other was pretty much clear. Sam obviously took advantage of this - I saw him outright staring at me at least twice. I'm sorry, @georgealmighty the thought of smiling or anything just flew right out the window. But I'll try again. Promise. And I will this time.
