\opening{Dear Aldo,}

Herby I write you a letter which has been made at the very last moment. Much better it will not go, definitely nog with all the errors which show up at the last moment. With the letter I would like to ensure myself to do things not at the last moment any more. Otherwise things can co horribly wrong.
\closing{So, for next time...}
