I visited Vietnam just to visit the Chu Chi tunnels. I found some parts of the War Remnants Museum horrific. I was in tears and had to wait outside for my husband.
In HCMC I was helped across the road 3 times until I mastered it. Once by a police woman, the second time by a group of school girls who then gave me a Vietnam Flag key ring and the last time by a lady spruiking her beauty wares outside of her shop. She raced across the road, dodging bikes, cars and buses to usher me across then usher me upstairs to her beauty salon. I 'repaid' her kindness by visiting there every day for numerous heavenly treatments with my hubby and one lazy day we went morning and night!
