How to help others dance under control…

Show by example (during dance). Talk to them well after an observed uncontrolled dance move (so you aren’t angry)
Don’t do it during the dance or when you are angry. They probably don’t know they are being a dance menace.
“It’s more comfortable for me if you do/don’t do X.” (or during dance “Please do/don’t do X” – explain more after the dance that it can hurt people, etc.)
Callers can help! Callers can warn about dangerous moves or figures, especially with newer dancers. Buzzword: “safety talk”
Callers can also call attention to observed uncontrolled or dangerous dancing without calling out a specific person, which can be a problem with #1 above.
Individuals and the community should praise/respect/laud in-control and otherwise good dancing
When someone hurts me during a dance, I say “ow.” If I have a chance afterward I’ll let them know what happened.
Callers can give style/safety tips by saying: “It’s more fun if you…”
(three checks by above)
Use the twirl with caution – always guide the “twirlee” into the next move. Make sure they are not thrown off-balance.

Teach “giving weight” in swinging! Teach beginners style! Because otherwise they’re like limp noodles.
