Lately this rule

 
Those who don't understand—
don't stop for them.
Those who do understand—
don't stop for them either.


Those who don't stop you—
don't try to understand them.
Those who do stop you—
don't try to understand them either.


When sleep comes, sleep;
keep the door closed.
When sleep won't come, don't sleep;
keep the door closed.


In the room where you feel good,
keep a door in that room.
Make the walls strong too.
The wages of the builders
who made your room—
put those in your own pocket.


They will come. They have to come.
Let them come. When they do,
a cup of tea with two biscuits.
Keep a small table outside the door,
with a stool or two.
