i work for a law firm
Oh, what's that like? My cousin is a lawyer but don't know much else about that
yea well the firm is just like a business entity formed by one or more layers to engage in the practice of law
It must be hard work, do you know much about how it operates? 
well they are organized in a variety of ways, depending on the jurisdiction in which the firm practices.
Are there many different types of law firms, like family law ?
well in the US you must complete the bar to have ownership that is a standard by the american bar association
I've heard people talk about how difficult it is to pass. Good thing people can retry 
yea admission to practice law is acquired when a layer recieves a license to practice law and it takes about 3 years
