Intriguing

It intrigues me that one sentence has different meanings depending on the context of a  situation.  
I was at  the park with my son and his friend today.  A little girl was having trouble waiting her turn to go on the swings.   Her dad said to her,  "Go after the boys."  
Such a sentence could mean  that she should  take her turn after the boys are  finished.   It could  also mean to chase the boys.
