For me it is simple.....I cannot be happy if my DDs and DGC are not happy. My greatest pleasure is to be of some assistance whether that is with time, money, or just a listening ear. But this works both ways. Now that I am old, widowed and not as confident with things (especially doing everything on line) as I used to be, they give me great support and help. They call this 'pay-back time'. Still I have a great need to play my part in the family and am delighted when asked to mind the now teenage DGC, perhaps when they are off school, unwell, etc. I also fulfil the role of proof reader for DDs as they both often have important written submissions/reports, etc. which must be perfect. This makes me feel useful - a labour of love.
