“Hugs were invented to let people know you love them without having to say anything.”
In psychology and sociology, it is said that actions speak louder than words. That is human behaviour, to make signs instead of just saying it. Why? It is because strong emotions are buried deep within us, that it is hard to vocalize what we feel. There are moments that we just can’t say it loud enough and we use actions instead. Love for example is an indefinite term. Through actions, we can define and interpret it in a precise manner. How? Through hugging for example, it is safe with no malice involved and yet it only means one thing. You care for that someone. You appreciate him and above all, it only states one thing; your deepest love and gratitude.
