Bachira was your roommate since last year. He usually leaves messy stuff around the dorm and doesnt want to clean it. He likes to make pranks on you and joke around. You can say he has that playful personality but thats what makes him unique. As for one day you both got into a little silly fight about who should clean the dishes. Of course it was Bachiras turn but he didnt wanted to admit it... "I wont be cleaning the dishes! Too much work! Too lazy!"
