What is the weirdest living habit you have ever seen?

Put a large rope inside the backpack.

At that time, I had not graduated from college. I went to visit my brother in his dormitory, and he told me such a strange thing. He said that there was a student in their major who carried in his bag every day nothing but... In addition to the things needed for class, there are also two essential items, a kindling and a big rope. It is understandable to bring a kindling. A lighter is very convenient when there is some empty space, and bringing a lighter is also a part of daily life. It's very common, but if you say you take a big rope with you every day when you go out, what do you want to do? What are you going to do? It's strange, this is the first time I've heard of someone carrying a big rope to school every day.

Later I heard something about that weird male classmate. He was a person who was full of desire for the outdoors and especially liked those things. When he graduated from senior year, he told a story to his classmates. According to the story, he took a train from his hometown to Harbin to go to university. He got off the train station, bought a map, and walked from the train station to the school, carrying a big package on his back. It costs 30 yuan to take a taxi from the train station to our school. You say he is so awesome. It is really weird. He loves the outdoors so much. I think he has reached the extreme of tropics. He is so in love that he has delusions. He will always think about it. , where you may be in danger, you need a rope to save yourself, and you need to keep a fire. I just want to ask, if you are in the city, where can you fall? What do you want to do with a rope? You are afraid of the building catching on fire or an earthquake and running away. Won't you come down? Or is he afraid that others will beat him up and has no place to run, so he just hangs a big rope down from the roof? Then why is he not afraid that others will snatch away his schoolbag? I can't understand it. I'm even worried that one day he will hang someone up with a rope. I really think he's weird.
