Personal Space

As being one member of the society, we couldn's avoid interacting with other people.The distance we control is quite important for us.We may always need our own space and we also try to keep certain distance away from others.This is quite normal in our daily life. When we are in the hospital waitng to see the doctor, if there is only one people sitting on the seat, you may certainly choose to sit several miles away from him and try not to sit very close to him.When there comes the third people, he would choose the seat both far away fron you two. When there are only two seat left beside one people,one would propabaly choose the seat which is further from that person. Then people would take the seat closely beside him into their last considerration.
   We are all accustomed to a certain distance with others. Everyone has their own distance which could be called the safety distance.They regard the area belong to the safety distance as their own personal space. Only in this space will they feel safe and comfortable. Once someone rush into the privata area, they would lose the sense of security, And they would be much more vigilant. Therefore, people all try to keep their own space be safe and not be violated by others.
     However, somtimes we have to give up maintain our space as it's unaviodable. For instance, when you are on the crowd bus, you even have no place to stand. So you must give up your personal space then.
