First, the dormitory never mops the floor.
This is the most common problem in dormitory. Maybe when I first entered the university, everyone would politely mop the floor, but after getting to know each other later, everyone's nature appeared. Many friends are like this and never want to mop the floor. When I first felt that the floor was a little dirty, I still chose to mop the floor, but later I found out that people didn't pay attention to such cleanliness, so I didn't mop the floor.
Second, littering, unwilling to empty the trash can.
Although there are trash cans in the dormitory, my roommates all like to eat snacks, and they all like to eat snacks in bed, so they often litter in the dormitory. This behavior leads to snacks in my dormitory, on the floor, under the bed and sometimes in the bathroom. They don't throw trash cans after eating, but there are three trash cans in the dormitory, which are full in less than a day, and no one wants to go downstairs and empty them quickly. Sometimes I put all the rubbish into garbage bags, hoping that someone will pick it up and throw it away when I go downstairs. So this is also a problem. Everyone is a collective, and if everyone doesn't take care of it, it will lead to such a thing.
Third, the clothes were not washed.
This is actually the most common. One of my three roommates is not bad. She washes clothes every day, but others don't. They wash clothes once a week. More than a dozen pairs of socks are thrown on the floor in front of the dormitory bathroom, and their clothes are also thrown at will. If there is a bucket, put it in the bucket, and if there is no bucket, just throw it on the ground. I sometimes see someone soaking it.
For such roommates, I lived with them for a year and a half during college. Because I moved out later, I won't be affected by those dirty environments, which is also a relief. So, if you love cleanliness, if your roommate doesn't like the feeling of cleanliness, sometimes you will be angry. Such roommates are really irritating. Why can't you love cleanliness? Is it that hard? I think these roommates are really outrageous, either with low quality or a lazy habit, which gives people a very uncomfortable feeling.
