A hug is a near universal form of physical intimacy, in which two people put their arms around the neck, back or waist of one another and hold each other closely (Wiki).
"One of the best feelings in the world is when you hug someone you love, and they hug you back even tighter."
"A tight hug can do so much for someone that is hurting."
"A silent hug speaks thousands of words to an unhappy heart."
Hugs from behind are wonderful.
Long hugs are beautiful.
Feeling that connection with someone is a fantastic and sincere form of giving affection. Hugs are honest, frank & can be used as a barometer.
& you usually can't give a hug without getting one in return.
Hug someone you love.
