Imagine if you will an adorable Kenyan child between the ages of 5 and say 9. When they are roving around in a group and they see a mzungu (white person) they will muster the courage to greet me with, "How are you?" But this is a special How-are-you. It has a certain sing-songy lilt to it and is often repeated over and over until you respond. They hit a particularly high note on the “you.” The result is a child-voice chorus of little people following you around chanting "How are you, how are you?"
Well, some cleaver mzungu made that into a ring tone for you mobile phone! I haven't downloaded it yet, but if you want to get the idea - here's the link. I might have to use this! And if you've ever experienced this you might have to too.
