And then Bryony is gone; gone too quickly - without a proper goodbye - for three days of work experience in the textile and costume department of our national museum.
Kitty and I breakfast in the airport on pain au chocolat and coffee, and are back in time for school at 8.30. It feels like a full day already. But of course there are more treats, messages, friends and gestures of celebration...
including a visit to see Grandma.
"This is the best birthday I've ever had", says Kitty.
I'm sure she has said that before, but the highlights of a day seem to take on special significance when it's your birthday and there were plenty of highlights for Kitty today.
