A hug says more than words ever can. It lets the other person know you care, you are there for them and they aren’t alone. Being embraced by another when you feel down, is a gentle reminder that there is always someone with you.
For many whom may not have grown up with a good system and strong relationships, may find a hug the embrace they needed.
When someone you know looks upset, see if they are ok and give them a hug, you may be the only person that day who has.
