Close your eyes and remember the last time that you were hugged. Two arms wrapped around you, the warmth it gave you, but above all, it is what it represented. A hug is a symbol of nurturing and caring. Taking something into your arms and squeezing. It is not only good for the receiver, it is good for the giver.
Hugs bring people together.
It is something personal you can give someone and it is yours alone. No two hugs are the same. I am sure you have. We all have. You look at their face and although you do not know the person, or what they may be going through in life, you sympathize.
