"Light sleeper"

Chloe and Emily had a sleep over during school holidays ( before they went back Melbourne for vacation). The girls had a wonderful time chit-chatting and playing LPS whole day ! 

Finally, it's bed time and Yaya said, "Mama, can we have the light on?" 

"Why?"

The girls replied,

"Because we are light sleeper."

Oh, so that's what "light sleeper" meant to them. LOL
