When someone travels and is out on the road, visiting strange lands, they will end up interacting with strangers. Besides the basic need to communicate for travel or information purposes, one also needs to reach out for the need of social contact or conversations. For those who feel hesitant to talk to strangers, they will slowly realize that it is not difficult and when you are out there on the road, traveling by air or simply visiting one place to another, everyone is on the same plane. Without the limits or identities that we are used to in our home place or address, you will find it more natural to speak to strangers and find yourself connecting with them at a basic level.
Travel usually leads to a more relaxed frame of mind; when we are not bogged down or biased about who we are and whom we should be speaking to, you open up and become your natural self. One does not need to be in conversation with strangers but feel comfortable being surrounded by them, trusting their presence and finding it non-intrusive. With a relaxed frame of mind, people end up making more friends as common topics are discussed such as what a new place has to offer to travelers. Indeed, places like hostels have seen friendships formed that have been long lasting; however, it is important that one should not develop expectations from such friendships, but allow them to be positive and natural; often it is hard to stay in touch when one is constantly on the road.
Hence, for a nomadic life, it is best that one does not have expectations or become emotionally dependent on a friendship that is formed on the road. On the other hand, when you develop the sense of being comfortable when surrounded by strangers that is a real learning about how we are all connected at a basic level and are among fellow travelers of life.
