Prudence is Occupied

The market is always open

But stalls have keys

The trader is always smiling

But goods go home with buyers

Visitors may knock

But lords guard the door

Sailors may play around

But fishes run the deep

The global space is free

But rooms have capacity

The lessons are liberal

But teachers are chosen

...

Scorners are always idle

Pupils are always waiting

Schemers are always lurking

But deep sea is always full
