"Fist Bump"

Note for the folks at home: If you are a foreigner walking through rural Kenya, expect one of three responses from local children: 1.) A group may urgently scream "HA-WA-YU!" at you from great distances, then run to your side to greet you with a handshake. 2.) [More common] "Give me candy!" "Give me five shillings!" 3.) [Most common among the very young] Bursting into tears and fleeing for safety.
... or, maybe I'm just a particularly scary-looking white dude.
