I may be a few minutes late this evening, though I assure you I will be there, and am certainly looking forward to our little rendezvous. I have no idea whether or not I spelled that correctly, as my French is sub-par at best.
To tide you over, here is a small Muggle photograph, taken from my personal collection.
If you let this slip into the wrong hands (i.e. any hands but YOURS), consider our friendship over. Just a warning. I trust you will be discreet.
Eagerly anticipating our meeting,
-A.L.
