There is difference in personal space. The
space in the lift is small, wherelse space bigger in mrt, bus,
school. Hey, there is something about personal space that we ought
to know. Sometimes if you are too near a person like in the lift
and are stillstrangers, you may scare the gal off when you approach
her. As for in the bus, mrt and school at least there is more
personal space for her. Aiyo, is this much that I know how to
explain. YOu may wanna read on personal space from books which talk
about how this can affect.
