Erro em trigger

tenho a seguinte trgger:

DELIMITER |   
  
    CREATE TRIGGER tgteste AFTER INSERT ON endereco
    FOR EACH ROW BEGIN   
      insert into teste values(0,'aaaaaaaa');
    END;   
  
    |   
DELIMITER ;

mas da este erro:
Can’t update table ‘teste’ in stored function/trigger because it is already used by statement which invoked this stored function/trigger.

pq este erro?
