The author and her companion traveled by car from Arusha, Tanzania, to Lusaka, Zambia. The trip was supposed to take 40 hours, but in the end it took more than 60.
The journey was very hard. The car was crowded, and some people could only sit on buckets.
But a Maasai man warmly invited the author to share a meal of lamb, which made her feel very touched.
At the border, there were even more problems: the information was unclear, the time kept changing, the crossing was very slow, and they still had to walk on muddy roads while pulling their luggage.
After arriving in Zambia, the car was old and crowded, and when they ate, they were charged double because they were foreigners.
Finally, when they took a taxi late at night, the driver suddenly asked for more money, and when they refused, he left them by the roadside.
Although there were many troubles along the way, the author still saw human kindness.
She thought about how animals on the East African savanna can migrate freely without passports and without so many obstacles.
She hopes that travel between African countries can become fairer and more convenient, so that people can move around, learn, and develop more easily.
