Perhaps I Didn't Explain Myself Clearly

"Sirs, in relation to the letter of rejection that I have recently received,"
"I believe there has been a misunderstanding."
"What I wanted was for you to publish my novel, and send me fifty thousand dollars."
"Perhaps I didn't explain myself clearly."

Notes:
Many nouns can be formed from the 1st person singular form of a verb: rechazar - to reject → rechazo a rejection, disparar - to shoot → disparo - a shot etc.
In the third panel, the imperfect subjunctive (the past subjunctive) is used since Snoopy is referring to a wish that he had in the past.
