First they start with a bit of their life story about how their background doesn't support it.
Then they give me lots of well thought-out reasoned explanations as to why it's hard and why they can't do it.
They attempt to persuade me into believing them and agreeing that it's simply something forever beyond their grasp.
Most of them succeed. Some of them overcome any amount of objections I can come up with.
Which actually kind of proves they have all the required skill for writing great salescopy.
Pretty funny, no?
EDIT: I'm sad the mods moved this to the copywriting forum - it's not REALLY about copy, it's about not being a puss.
