Cold in the Congo?

So folks....it is now the "dry" season.  There really aren't seasons like summer, winter, fall and spring here, just wet and dry.   So here we are in the dry season.  Whoa, do we ever love it.   We enjoy a cool breeze and much less humidity during our morning walks and have found no need  to wear anything long sleeved.  However, the Congolese are freezing, agonizing that the temperatures have dropped to as low as 70 degrees in the evening.  One morning we came out and found one of our guards, Jean -Claude in a knitted stocking cap and sweater.  It was really difficult not to burst into hysterical laughter.  Then we were invited to the home of one of our other guards, Arthur and his wife Agatha who have produced Prevot an adorable little boy.  Agatha proudly presented Prevot to me to hold.  I almost couldn't find  him.  He too wore a knitted stocking cap, pajamas, a wool knitted sweater and was wrapped tightly in a heavy blanket.  It had to be a good 80 degrees in that room, I was hardly able to breathe it was so hot and I had on short sleeves.
