Happy World Hello Day👋🏻👋🏽👋🏿! World Hello Day was created to express that conflict should be resolved through communication rather than the use of force. This demonstrates the importance of personal communication for preserving peace. All you have to do is say hello to at least 10 people today. Say hello to someone next to you, in the comments to this post above or below you, care for one another and make the world a better place! 🖤Ben.
