I am a full time dancer and once in the toilets after I'd been and I was waiting for my mother, I was dancing and a lady thought I needed to "pass water" so how do I dance without looking like I need to "go"?

Seriously? If you're a dancer, then you know how to dance. You know the moves of a dancer and you know what you look like when you do a potty dance.  So you're either spamming the site or the woman who was observing you when you were "dancing" thought you might be having a seizure and needed to "pass water".
