A study shows that the secret of domestic bliss is having two daughters, the Daily Mail reports.

Researchers found that two girls are unlikely to fight, will play nicely together, and rarely annoy their parents.

They also make little noise, seldom ignore each other and are more likely to confide in their mother or father, scientists claim.

But doubling the number of daughters is a recipe for disaster, with parents of four girls the least happy and reporting an average of four fights a day.

家有兩女最幸福

???????據英國《每日郵報》報道，研究發現，家庭幸福的秘訣在于擁有兩個女兒。

???????研究人員稱，兩個女孩不大可能打架，她們能很愉快的一起玩，很少使父母生氣。

???????她們還不怎么吵人，很少會無視對方，而且更可能和父母推心置腹。

???????但是如果女兒的數量翻倍的話，就會帶來“災難”。有四個女兒的父母感到最不幸福，因為女兒們平均每天就得打4次架。
