First post, last letter

I'm starting this blog as a repository for all the letters (electronic or otherwise) people receive from those who, after a first date, are trying to signal nicely that they'd rather have their hair done by a chainsaw, with a dry from an aged perv's panting, than go on a second date.

Here's one:

"Secundus,
Thank you for taking time to meet me. Just wanted to let you know that I am happily seeing someone else.
Good luck to you,
V"

Notice the "good luck to you". This or variants on it will be a recurring trope; the message is that the writer sees no future interaction.
