BY: BY drop.
Mummy: No, BY fall down.
BY sees the toy rolling off the table onto the floor
BY: (pointing at the toy) Fall down!
Mummy: No, toy drop.
BY: Toy drop! ...Good boy! *clap*
Mummy: Yes, BY good boy! *clap*

A while later....
BY trips....
BY: Drop!
Mummy: No, BY fall down.
BY: BY fall down.
Mummy: Yes, BY fall down.

During dinner....
BY spills some soup on the table and it travels to the edge, onto the floor
BY: Fall down
Mummy: No!
BY: Drop!
Mummy: No! Water DRIPS!
BY: ???!??

Mummy: eh? if water drips, why are they called water droplets and not water driplets? Now Mummy's confused too! Hahhahaaah!
