It was a slow rub on the arm. From the elbow to the wrist. With a deep look in the eyes and a smile. I have fond memories of that. It was only done when at parties as we were off talking to different people. Time would stand still for 5 seconds. I miss the hugs as well.
Human contact. Very important.
Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul. unconditional love is awesome!
