Is kiss a way of showing off one's effection

Hugging and kissing someone is for me a sign of love and affection which doesn't exclude friends no matter whether female or male

It is one of the methods of showing affection and love. In some countries, they hug each other In some countires they shake hands In some countires they fold their hands (NAMASTHE) In several countries, they bend their body If you have heard of Freemason, do you know what they do, when they see another freemason?

Yes a kiss is a way of showing affection toward another person. Not just a spouse or a partner, but everyone I care about, My family is a kissie, huggie bunch of people.
