Back in Manchester

Walking back from an excursion to the south, 3 kids on bicycles passed by. One of them called out '你好' in Chinese. I responded '你好'. Another one kid followed up, and called out '你好' too. I responded as well. They were quite satisfied to ride away.
I was surprised, but also felt happy about being 'acknowledged'. The kids might feel the same way.
I think education is quite important. The kids, not like in other cases, didn't see me as a threat; rather, they acknowledge my presence. If kids are taught and learn how to respect different cultures, then they will learn and know how to respect nature.

The 'mutual acknoledgement' should've worked for many situations, including the eco-promotion between government level and the local communities.
