Jackass

He had a donkey for sale so he wrote to his friend who fanned in Wexford.
Dear Mick, If you're in need of the best ass in the country don't pass me by.
Yours,
Jack.
Mick replied: Dear Jack,
I'm not interested in your ass or anybody elses either.
Yours,
Mick.
Could the foregoing be called 'Letters of a Jackass'?
