Girls,next door please

Not too long ago Lecturer : It's against the medical ethic to have any relationship more than a friend with your patients. You might end up in trouble with the licensing medical board if you marries one of your patients. You might get your medical license suspended. Suddenly all the guys straightened up and start to pay attention,I groggily turned to D, Xiao : D,you know what that means? For every girls we see as a patient, we lost one potential wife. D : Awww......man. Pray pray no chun chicks come to see me next time Xiao : I just realised something.I think we just heard the reasons why a lot of doctors we seen are still single. D : Yeah,me too. Those who want to have doctors as their potential spouse have just thrown away their once-in-a-lifetime chance when they stepped into our clinics. Xiao : A grim world indeed,a grimmer world for all of us here. D : Darn it man,that's so sad after all we toiled our asses here. Xiao : I think I have a way around the system. I think I gonna take up obstretric already. D : (pauses for a moment) For a minute, I thought you were sleeping through class. *smile*
