How do you explain Internet/BGP/ASN to your non-IT friends ?

It is not really easy to explain BGP/ASN concepts to a non-friendly-IT friend. I am really interested in how you explain this. Just to know. I am really curious.

Do you use an analogy ? Which ? Do you go directly in technical stuff ?

To begin : for my part I use an analogy around city/country. I explain that city/country announce to others her streets or better a set of streets. and so on …

It could be cool to know your stories about this…
