Med school is very much like a very small society of its own. It's got its own laws, and it's own culture, as well as it's very own religion with it's very own god (The Cofee God) and its own altar : the coffee machine, where everyone meets up at least one a week. To catch up. And compare whitening of skins and darkening of eye circles.
Being a med student is like playing the russian roulette, but with a little twist. You aren't playing your life here, but rather your whole semester. As you're betting on what type of tutor you will get for the next four months. Which, in turn, will determine how much suffering and pain you'll live for these next months, basically. You unfortunately don't get to choose your tutor. You get assigned a doctor, and follow him/her for the whole semester once to twice a week. Your experience can range from total bliss, to total disaster.
