I get the same complaint about parties, as ours were always 'the best' when the DDs were wee, just as my DM had put on wonderful parties for my sister and me. My DGD have themed (eg,Harry Potter, with wands and photos of the guests flying, etc and my favourite an indoor Beach Party in February, complete with an inflatable pool, sand pit, deckchairs, palm trees, Caribbean music and an ice cream stall) I get dragged into help because 'it was me that set the bar so high.
It is also my fault that they HAVE to grow fruit and veg in their gardens and make jams, jellies, soups and stews.
