challenged
I agree that the quantity of your challenging questions, which would put Question Time hosted by Heinrich Himmler to shame, are a bit of a b̶o̶r̶e̶ chore.
Someone asks a simple question like "What is a clay brick made of?", and you ask 50 questions ranging from what they had for dinner last Saturday, what size shoe they wear, where they went on holiday in 1987, and what the bloke six doors down thinks of post modernist art.
And then, you want a DVD full of pictures, including electron microscopy and ultrasound.
And then, you give a poxy answer that will take six months and £5.4k to carry out instead of a Sunday morning and a couple of quid.
That's what i find challenging.
