There is so much we learn about ourselves when we travel. Our lives are a compilation of all the experiences we have been through, that radiate out of us to reveal who we are today.
It is interesting to think that every person that I meet traveling is only seeing one side of myself: the person I am in the environment I am in at the time, yet all the places I have been have a remarkable influence on who I am at that time.
There is so much depth to every person we meet, that it is impossible to assume we ever know someone completely. I think this curiosity is part of what makes our relationships with each other so fulfilling.
