It’s been a while since I’ve done the spotty dog or the grapevine but at Saturday’s party I felt myself invaded by the spirit of Jane Fonda. The evening had started out all cheese and wine and small talk about fridge freezers. Then, before you could say Smeg, I was in a twizzling frenzy with a boy from Brazil. Unlike parties of yore, there was no prospect of a rummage in a downstairs cupboard so I settled for legs akimbo on an Ikea rug . In fact, at one stage I went all Beyonce and got down  on my hands and knees and stuck my bottom in the air. Oh what larks!
