In South Africa

and awaiting my flight to Nairobi with a final destination of Djibouti.  I misjudged the flight from Atlanta to Johannesburg; it was actually 15 hours and I'm really tired right now despite the fact I slept about six hours on the plane.  I will board the flight in about 90 minutes but won't arrive in Djibouti until about 11 hours from now.  Please check my grammar because I'm kind having blurred vision at the moment!
