There is a big big difference between being "alone", and "lonely".
Being "alone", means, that you enjoy your own company and the solitude to do things, that are meaningful to you.
Being "lonely", mans you need to have others around you, to feel good about oneself.
A touch, hug can be healing, if one has true affection, for another peson. We all need human contact in our daily lives. Laughter is the best medicine.
People who need people.......
