This is really interesting. I do not hug people very often, but sometimes it is nice to get a hug. And sometimes getting a hug makes me cry, if I'm too stressed and upset. And sometimes I hug people who are stressed and upset, and they cry. And that can be really nice and cathartic, I think.
Awww yes, yes and yes. I can feel and relate to what you said and yes hugs can really relax you and even make you cry when you are really emotionally stressed and frustrated. Great commenting man! :)
