Americans are like children: noisy, curious, unable to keep a secret, not given to subtlety, and prone to misbehave in public. Once one accepts the Americans basically adolescent nature, the rest of their culture falls into place, and what at first seemed thoughtless and silly appears charming and energetic.
Visitors may be overwhelmed by the sheer exuberant friendliness of Americans, especially in the central and southern parts of the country. Sit next to an American on an airplane and he will immediately address you by your first name, ask "So-how do you like it in the States?", explain his recent divorce in intimate detail, invite you home for dinner, offer to lend you money, and wrap you in a warm hug on parting.
