Maybe the ones who will not look you in the eye are shy.
Hopefully the ones who stare at you are not trying to intimidate you.
Eye contact is very helpful for visually leading or creating chemistry or connection with your partner.
Maybe you are trying to read their minds or projecting what they are thinking. Maybe it is not about you, but something they are dealing with.
Feel confident and more comfortable in your dancing and do not feel put down or intimidated by their stares or lack of eye contact.
"Dance like nobody's watching."
Everyone is dealing with their own thinking and issues.
Don't worry about what others think, just dance and have fun!
