Whats do wazungu (white people in tanzania) and tandem bicycle riders have in common?

Saturday one week ago I was with Miku on the tandem on slow club ride.

 This is Miku at a tea stop.

 Later on when we are on busier roads he informs me that he doesn't like being on the tandem.  "Everyone notices you and comments and stares.  Makes me uncomfortable."

Now he can relate to what I feel like as white dude moving around Arusha.
