where clause on a left outer join

Hello, let's suppose I have the following tables:

create table parent (  parent_id numeric primary key,  parent_data text
) ;

create table stuff (  stuff_id numeric primary key,  parent_id numeric references parent,  stuff_data text
) ;

And the following data:

crisdb=> select * from parent; parent_id | parent_data
-----------+-------------         1 | aaa         2 | bbb         3 | ccc
(3 rows)

crisdb=> select * from stuff; stuff_id | parent_id | staff_data
----------+-----------+------------        1 |         1 | xxx        2 |         1 | yyy        3 |         1 | zzz
(3 rows)

I wish to write a query that returns all rows from "parent" and, beside 
of them, staff data with stuff_id=1 if available, otherwise null.

The following query:

select  par.parent_id,  stu.stuff_data
from  parent par left outer join stuff stu  on (    par.parent_id = stu.parent_id  )
where  stu.stuff_id = 1
;

Gives the following result:
 parent_id | stuff_data
-----------+------------         1 | xxx
(1 row)

But this is not what I want.

The following query:

select  par.parent_id,  stu.stuff_data
from  parent par  left outer join  (    select      *    from      stuff    where      stuff_id = 1  ) stu  on (
par.parent_id= stu.parent_id  )
 
;

Gives the following result:
 parent_id | stuff_data
-----------+------------         1 | xxx         2 |         3 |
(3 rows)

Which is exacly what I want.

I'm wondering whether there is another way to get this result, without 
using the online view.

Thank you. Kind regards,
