An old Jewish tradition, that's new to me

As you may know, we are leaving on June 10th for two weeks in Spain and Morocco.

A friend was just over, and, as she was leaving, she handed me 2 dollar bills, saying that I should give them to someone in need. She explained that it was an old tradition, when someone is going on a journey, to do this.

I had never heard that one before, but I really like the karmic balance it implies. As everyone knows, the highest form of charity is when the giver and recipient do not know each other.

Nice, huh?
