Hugging oneself

I was stopped at a traffic light across the street when I noticed this homeless man doing an intricate little dance on the sidewalk.  By the time I got my camera out and snapped it, I caught him stopping and hugging himself. I wondered what made him pause like that.  But we all need hugs and I mentally hugged him too.  I am hugging the world today and sending peaceful energy...as we've had one more awful shooting caused by a mentally unbalanced person with a gun.  I can't stand the obsession with guns.
