So I took out my little pad and wrote down 'shopping list'.
I preceded to write 'Pepsi' and 'satsumas', fairly normal shopping, and then turned it up a notch by adding 'heroin'.
He didn't notice.
I continued to write absurd and strange things broken up by clusters of normal things.
Eventually I ran of space on the page and just left it on the desk between me and him.
Here is the full list...
He tapped me on the shoulder and said "Tinsel and lipstick, Are you secretly a cross-dresser?"
My response, "Sometimes".
He then listed all the drugs I'd written and said I must have quite a weekend planned.
I said "It's amazing what you can buy in Asda".
So basically he wasn't nosey enough to read over my shoulder while I was still writing the list, but he did read it afterwards. I think that gives him a score of 4 on a scale of 0-10, where 0 is completely ignoring and 10 is News of the World.
P.s. Apologies for my poor handwriting.
