yes, be hug-positive. No hug shaming!

Though, with that said, I don't initiate hugs with people at work, and I personally find it a little weird to be hugged by someone during regular hours. After hours and that weird/special moment when a person is leaving the company are exceptions. When you can drop the professional veneer, and have absolute permission to just treat the person as a real, actual human being ... those are great.
