Last Wednesday I received an invitation from the Prime Minister's chief spinner John McTernan to attend Christmas drinks at Kirribilli House.

The invitation was a little vague, not requesting my attendance as a "woman" or as a "blogger" or even as a "mummy", but simply requesting the "pleasure of my company". I had eight hours to RSVP and did so immediately before asking around to see which other media colleagues had been invited. It wasn't long before I realised the group invited was a similar one to those who attended the PM's morning tea with "mummy bloggers" back in June, with the exception of a few additions like me.
