Sometimes it can be hard to meet and get to know the people who populate the world around you. Walking up to strangers and introducing yourself is a difficult thing for most people to do, but simply saying hello is the first step to getting to know someone. World Hello Day is a holiday dedicated to saying hello to as many people as you can. Try to say hello to at least ten people who you normally wouldn’t speak to on this day. You might be surprised how many of those greetings turn into deeper and more fulfilling conversations.
