selfish people

Recently, we all prepare for our final exams, therefore, as you can imagine, the library is crowded full of people. Not that the seats are unavailable， some people take two or more seats for their convenience so that they can place their books , coats or something. That was not what pissed me off. What really pissed me of was the monitor of my class, who had taken two seats and felt proud of it. So i made an ironic remark. Unbelivably, she replyed that if i could get to the library earlier, i could do the same. She said it in a bitchy way and felt no guilty and sorry.
