Dear Coronavirus,
It’s without a single regret that I have to reject your offer of taking me to a journey in which I have absolutely no intention or interest to participate. For your information, I’ve herewith enclosed several points to highlight why. I sincerely hope you’ll find them convincing and I also hope our tête-à-tête meeting will be timely postponed to an unidentified future.
So, here are the issues I’d like to identify and draw to your immediate attention.
Yours sincerely,
