It's been some time since our last contact, but I assure you it was for your own good. Yet - there's an urgent matter for which I will require your assistance. The location is same like the first time we met, and the time is your to choose. Please, do not let me wait.
Your message said it was urgent. As such, I have flown with all due haste to our previous drop off point. I will remain on site until we can resolve your very important matter.
