摘要: Borders separate political blocks, nations, states, communities and also your house from that of next-door neighbor. Some boundaries are easy to cross, others more difficult pass. But no matter how liberal or restricted neighboring policies are, all slow down may even stop communications. At the other hand, “lines defense” displayed, for instance, along a national border will throw considerable light on state philosophies behind it without having first-hand knowledge about two governments in question. Or take vicious dog gnashing his teeth side fence. He certainly does not encourage friendly visit, but reflect something master’s mind.
