 Person1:      Have you treated any real emergencies ? 
 Person2:  Well , they took us along with some paramedics.There was this guy who fell off his motorcycle and suffered a concussion as well as a couple of compound fractures . His wounds were pretty serious so they had to rush him to the hospital . It was intense ! 
 Person1:      I can imagine ! I tend to faint when I see blood , so I think I won ’ t be taking up a course like that anytime soon !
