"Loneliness is not feeling part of the world. You might be surrounded by loads of people but... you are [still] lonely."
We are living in a world full of lonely people, many of which we don't know are lonely. This photo is exposing the fact that even the least expected people can be found to be lonely (my 10-year old sister). To be lonely is a horrible feeling, and we've all felt it at a point in time, so why not make the people around us feel like they belong?
Be kind to others. Unless you're really close to them, you probably don't know what they could be going through. Surround yourself with people that make you feel significant! There will always be people who will bring you down, and perhaps label you.
On that note, I hope that you have a great day! P.S. you're amazing just being you!:)
