Another type of inconsiderate fools that exist in my hostel are those Indians who play football in the corridor. I don't mean to stereotype, but I've only seen Indian students doing it. They would block people's way and shock me whenever their ball hits my door.
Another inconsiderate fool, this time mainly Chinese students, is the one who turns the volume dial all the way up when playing shoot-'em-ups. In certain group games such as Counter Strike, they'll also be shouting commands, jeers, and laughters to their friends in nearby rooms. Thankfully, this group resides at the opposite end from me.
