Our son put us in touch with her.  Said she was from his church and was coming out to Cameroon.  We began emailing even before she left the states.  And finally, now that her four months out here are coming to a close, today we found a free moment in both our schedules, and had her over for brunch.  What a delightful lady!  Turns out that this 75 year old widow and we have many friends in common.  It was amazing to sit out here in Darkest Africa and get caught up on one and then another of our friends.  What a small, small world!  Turns out that her daughter and son-in-law even go to church with another of our sons and his family.  And the world shrank some more!
