happiness is...

When the oxygen supply comes on again just as the child's saturation is hitting 78% and he can be bagged up to 98%.

The joy in children's faces as they run with the muzungus.

Listening to music on the drive to Butare – past terraced hills, banana trees in the sun, women with colourful dresses and baskets on their heads, farmhouses, rice fields and children everywhere.

Watching the residents have "eureka" moments.

Swimming and a hot shower at the Serena Hotel.

Teaching super keen students.

Sharing all this with Ariane, Brian and Daniel
