Hugging. Well.. hugging someone must be natural&sweet. Usually, the people who like hugs are nice and they want to make the world they live in happier. The best time to HUG someone is ANYTIME. Hugs don't have a value. Hugs are free.
There are many types of hugs:
-hugs that are meant to show someone you like him/her
-hugs that are meant to make your or someone's day better
-hugs that are meant to show that you really care about a person and you hug that person when he/she really needs to know that you care about him/her
-hugs that you give to a child -everyone likes hugging children, because that's a childish sweet thing and everyone misses his/her childhood... and children also don't refuse hugs-
-love hugs, missing someone hugs, friendly hugs and so on.
Hugs are important. They are one of the basic essentials of life.There's no limit on giving someone a hug.  Hugs are fluffly and everyone needs something fluffy at least one time in their life.

Go hugging.
