to some extent, know the problem but very different circumstances..... anybody from the next generation on (my gen as I am the same age as her) that you can encourage them to take out for lunch (or breakfast)?
For example, we have a couple of cafés here in Truro that are are great for mingling and networking.....I have just gained a commission off one contact for a drawing that way, a really nice guy who wants to get the drawing and prints of the family house, an old Cornish long-house - in which his daughter is now installed, as a pressie for her!
