nd 10:00 a.m.our car got stuck in the sand! We spent about three hours trying to pull out the car without any progress.Finally, we decided to walk.As it was hard for an old man or a young boy to walk more than 40km in the desert, I decided to get help myself.I took a bottle of water with me and started to walk south alone.I knew the way well, but it was a long way in the sand.I walked more than four hours without stopping.When I felt so tired and thirsty, I stopped to rest.I drank all the water and slept for around two hours.
