A hug is an embrace,

a form of physical intimacy

when two people hold each other closely.

A hug is a connection,

a kind of non verbal communication

that means comfort, friendship, love or affection

A hug is a general indication

that two people are familiar with each other,

shared between friends, family, siblings, mother and child.

A hug is replaced by a handshake

in some cultures when strangers meet,

though in other culture, it is a form of greeting.

A hug is a cuddle,

loving gesture of affection

freely given and lovingly received.
