It is this just-out-of-reach quality that lends affairs their erotic mystique and keeps the flame of desire burning. Reinforcing this segregation of the affair from reality is the fact that many, like Priya, choose lovers who either could not or would not become a life partner. By falling for someone from a very different class, culture, or generation, we play with possibilities that we would not entertain as actualities.
问题：请问play with在文中怎么样理解？
By falling for someone from a very different class, culture, or generation, we play with possibilities that we would not entertain as actualities.
play with: 在此为“巧妙地借助”。
that引导的是定语从句，that为关系代词，指代possibilities并在从句中作及物动词entertain的宾语。entertain在此为consider的意思，entertain A as B =consider A as B. as B为consider的宾补。
