Have you ever thought this? Ever voiced this to your friends? What's really important about dancing anyway?
I've attended many social dances and many competitions and must admit there is one dancer that I always enjoy watching on the floor. Have you ever seen the dancers that dance every dance (even if they can't dance?) but they're always smiling - always having fun. I watch these dancers in fascination, they are actually having a great time.
When I watch people on the dance floor, I often wonder, why are they dancing - they look like they're in pain? I am truly amazed that anyone would go out for an evening of torment and painstaking work - there is a time and place for everything in life.
Social dancing is people moving together on the dance floor and enjoying themselves. We don't all have to dance the same way. Even if you just get up and sway to the music, that's your way of expressing pleasure in dancing. Did you ever think to yourself, "They're not bad dancers - just different".
A dance floor will always have people with different styles and knowledge levels about dancing: which doesn't mean they are good or bad dancers, just people enjoying themselves for an evening. Maybe if you take dancing so seriously that you're losing your ability to laugh at yourself over a mistake it's time to take a lesson or two from a social dancer that doesn't perform ballroom steps but actually moves to music for FUN!
