The Free Hugs movement started with Juan Mann.
we were 3 people and hugged 232 people in 3 hours. not only that we weren’t banned by the police, a policeman even almost stopped the car to hug us. in the second hugging day we hugged over 400 people.
This can be done anytime and anyplace. I imagine all kinds of variations, even a modest version for frum communities. We can have men huging men and women and hugging women. We can have mixed hugging for those that want that. We can have kids hugging kids. Hugs are holy.
