How close is too close,in your opinion? I'm asking because I have experienced a lot of 'space invaders' lately. e.g. I'm sitting on the bench at the bus stop,a woman comes along stands literally 18 inches away from me,facing me,and starts talking on her phone. I know there's no law against it,and she's not harming me,but why stand practically on top of me when she has yards of space available around her? And the man behind me in the queue in Poundland. He was standing so close to me that I could feel his breath on the back of my head. No need for it IMO. I don't like strangers in my face,I think a 3 foot zone should be implemented.
