At the cafeteria

I had some time to kill before a class and I went to the cafeteria of the university. I sketched - with a modicum of success - some of the characters around me.

A girl fidgeting with the glass of coke and the omnipresent iPhone; another one almost sleeping on top of the laptop/notebook; a guy who seemed discouraged by the task in front of him; a girl who just finished her lunch and another one engaged in a vivid conversation where the hand was very eloquent.
