Omo and time
As his time was nearing completion, he said he measured time in any way possible. (He desperately wanted to return home to England.) One measuring stick was Omo laundry soap packets - each one lasted about two weeks. So he was able to say, "It's ten packets till I get onto the plane."
His wandering days are over. He married a Kenyan lady and is building a house in Karen, a nice suburb of Nairobi.
And for us, we're down to less than one Omo packet. On June 2nd, we board the out-bound plane, with no plans to return.
