I am Japanese girl wants to ask you something .
If someone(not your intimitate partner , who you meet first time )comes close to you , where is the borderline you start feeling uncomfortable??
I do believe each of us have a borderline.
as for me an extention of umbrella is my unvisible line . I start feeling uncomfortable when they come to me beyond this unvisible line too much .

Of course I am not talking about greeting hug and kisses.
Of course There is always exception. Rarely even we end up sleeping with them at the first meeting though.
In general ,Where is your borderline ??
Tell me your opinion please.
