What a delightful story, Terry! I know you'll treasure the memory of that night forever.
By the way, my hat's off to you for resisting (the almost inevitable) impulse to hit on her. That would have ruined a magical evening. Maybe she sensed that you weren't just another pickup artist, and that allowed her to relax and indulge in a little tête-à-tête with an intriguing new acquaintance. She apparently felt safe in your presence, and that's a tribute to your gentlemanly manner. Your offer of conversation without guile or ulterior motive was probably a refreshing distraction from her grief. Congratulations, my friend, for a good deed well done.
I obviously don't have your writing talent, but I did have a similar experience many years ago, and I thank you for reminding me of it. My first time in Europe was a two week business trip, beginning in Paris. I was to join a co-worker who was already over there, and who also happened to be an unusually attractive person of the feminine persuasion. Well, I was all wide-eyed tourist who was very happy to be over there on someone else's dime. I was also happily married (at the time). So when she saw I wasn't going to be hitting on her and that I viewed her as the professional she was, she relaxed and we had a great time. She later confided that her former team leader made her feel like he was gonna pounce at any moment, and she never could quite let her guard down. On the other hand, we truly were "just friends" who had a job to do, and we worked together well. We even had a four day weekend off in Milan. We took a train through the Alps to spend one of those days in Venice. We had a very enjoyable time, and there was never a minute when either of us felt uncomfortable or awkward.
Anyway, I do hope Veronica gets in touch and enjoys your story. Could be the start of a beautiful friendship...
Kudos, my friend! Keep those stories comin'...
