Singing

I like to sing and hum the "Papa Mama" tune when I'm happy or when I'm in an extremely good mood. It goes something like this...

Pa pa pa,
Ma ma ma,
Daddy papa
Mummy mama
Yeh Yeh Mah Mah

First two lines: Sung to the tune of "Ke ren lai" / mi-re-do
Third line onwards: Any of the six words in random, own tune

It's really cute but every time mummy grabs the camera, I will go into "mute" mode.
