It's all balls

Lovely J has decided to try sitting on a Swiss ball at work. It's good for core strength we're told. We could all do with a bit of that :-)
It was touch and go with swaying and rolling, and a bit of desk clutching. She does also have a wine bottle on her desk that she claims is full of water... We are a trusting bunch and are poised ready to catch her if she rolls too far!
