Hello, dont pull everyone inside. My parents, My school in mysore taught me to keep my suroundings clean.. I have always dont it where ever I go. Not just in US I never spit or threw waste outside in India. Keeping your surrounding clean is something you have to teach others by being a example. Teach little children to be clean that way your future will be strong. And grass surely is greener in US becouse they maintain their lawns. And will be arrested if they dont water their lawns.
Dont just talk what others have been drumming for a long time. go learn more about other countries cultures too.
