"Yellow Rock"(hug your corner) or "Red Rock"(hug your partner) are common signals to square dancers. "Hugging is a miracle medicine that can relieve many physical and emotional problems". Some women do not like strangers hugging them, so be a little careful until you get to know them. Most men like the tradition. In any case, "Have you hugged somebody today?"
Invite non-square dancers out to visit with you. Try to get them interested in lessons. Non-dancers may be afraid to start lessons. You should bring them to class until they are comfortable coming by themselves. Make friends and share the fun with those friends.
