Describe a behavior that many people may do in public that you find inconsiderate. When talking about the behavior that many people may do in public that i find inconsiderate, the very first one coming to my mind is that someone may talk loudly in a public place. As for why, i suppose that's mainly because it will disturb people around him. To be more specific, i can take my personal experience as an example. As a college student, i am always preoccupied with my academic studies. In that case, i am confronted with overwhelming pressure. so i need to enjoy a quiet environment in the classroom in order to have some relaxation. However some students sometimes made a lot of noise when i was listening to light music, which really annoyed me.
