One day when Jesus was going back to Galilee, he met a Samaritan woman at a well. He asked her for some water but he wasn't meant to talk to her because she was a Samaritan and he was Jewish and Jewish people hated Samaritans at that time.
Another story we read about how Jesus treated people was when he healed a man with leprosy, which is a skin disease with lots of sores and is very contagious. Jesus spoke to him and spent time with him before he healed him.
I learn from these stories that I must respect the tapu of others even though they are not like me because God loves everyone the same amount and we are born in the image of God.
