ofcours they should stand togather and also they should be too near from each other and that why we call them friends because it's to difcult to find someone stay with you in sad and happy Occasions

It's well established that Americans prefer some of the greatest distance of 'personal space' of any nationality. This is true between family, friends and strangers. http://en.wikipedia.org/wiki/Body_contact_and_personal_space_in_the_United_States Note, however, that evidence suggests that caucasian americans particularly prefer larger berth, whereas african americans tend to be comfortable at closer distances. http://www.jstor.org/pss/2786341 Personally? I like to put myself out of my comfort zone, but I try not to make others uncomfortable.

Definitely. Because without a distance you'll soon get tired and bored of each other and a friendship can turn into a habbit and lose its charm. I think everyone should maintane personal space and trust others not more than for 94%
