An excerpt for @pikethehedgehog I hope you enjoy it!
It is well-documented that humans have the ability to be very coordinated creatures. This can be seen in both a physical sense, where they are able to control their bodies in ways that allow them to be both beautiful and frightening, and in a mental sense where they can band together in large, well-organized groups that can move with ease towards a common goal. That being said, humans are not at all one-dimensional and can be just as clumsy as they can be graceful. Some humans are aware of their surroundings at all times and are careful to not disturb parts of their environment that should be left to their own devices. These are not the humans you need to be worried about. It is the humans that for one reason or another are less aware of their surroundings as they should be and as a result are particularly accident prone. Be it that they are physically unable to have this awareness or simply cannot be bothered to pay attention to the world around them, these humans can cause a number of disruptions to those nearby. Most of the time they are relatively harmless; they will trip and fall, bump into pieces of furniture, run into others, knock things over accidentally, etc. Usually this sort of thing is not a problem, the human will just apologize and everyone can move on with their lives. But, sometimes this behavior can be quite hazardous. For example, some humans can grow to be quite large. This poses quite an issue when in conjunction with a lack of awareness to their surroundings and creatures that are substantially smaller than them. A small bump from these humans could potentially be enough to send something or someone much smaller flying across the room and I am sure you can imagine the many ways in which this could be dangerous. A human with a lack of spatial awareness also causes issues when they cross paths with someone who has their arms full. Disaster often ensues in this situation and especially so if the items being carried happen to be fragile. So, when crossing paths with a human, it is a good idea to simply assume that they are not as aware of you as you are of them and either wait for them to pass you first, or make some sort of noise to announce your presence. Accidents cannot always be avoided, but it does not hurt to take measures to prevent them.
