Alas, if only it was...
Just been to the supermarket, it's expensive, and unfortunately they don't accept hugs for payment. Truth be told I didn't think they would accept my card...
In a nutshell...
cover letter
find 3 or 4 relevant skills, experiences or accomplishments that demonstrate your suitability as an independent researcher that is able to think for themselves - write about them. Don't suck up to the sup. Trend the fine line between arrogance and confidence.
I've said too much already... I have a couple of awesome coverletters that never fail to get me a job interview. Unfortunately, I do actually charge.
Good luck with the letter.
