Every day that I drive through the streets of Lagos, I see plenty of men in the act of urinating (women tend to be a bit more discreet). Some are modestly facing a wall, but others have no reservations about aiming their stream into the street. Sorry -- no pictures of that here. But there was an amusing picture posted on an LDS blog this weekend -- a photo of a sign that is in each stall in the Ghana Missionary Training Center. This is where missionaries called from this area go for their training, as they almost always stay to serve within West Africa -- they often stay in Nigeria for their mission. I think most LDS members have a little better hygiene practices than the public at large here, but still there are a majority of Nigerians who have no access to indoor plumbing and probably need some explicit instructions on the use of toilets and toilet paper.
I like the tip about repeating a scripture in your head while you wash your hands.
