The business writer Erin Meyer places the United States among the peach cultures described by Fons Trompenaars. In them people “share information about themselves, and ask personal questions of those they hardly know.” Further in, “you may suddenly get to the hard pit protecting someone’s real, or at least more private, self.”
MIT’s office for international students quotes the same image. Americans are “soft on the outside, easy to approach, but the pit is harder.”
