My brother got married on Saturday and we had a splendid day, culminating in a disco. It's ages since I had a good dance and my nieces (all in their twenties) were able to update me on a few dance moves. Believe me I needed them to take me in hand. Claire especially tipped me off about her 'in the supermarket' technique. Granted it's hard to explain and appreciate the full genius of this advice without showing you a video but darn it we forgot to record it for the nation.
Basically move your body and feet to the beat while pretending to pick items off notional supermarket shelves high, medium and low and then every now and again push your imaginary trolley to the music. If it's a particularly quick tempo then just empty the phantom items out of that old trolley in a maniacal fashion. NB If you are dancing and actually see or hallucinate supermarket shelves you have imbibed too much.
Apparently on 'You Tube' there are some Supermarket Cart Dances but I'd like to think my niece and her friend invented it. Anyway apply the moves to most music and you'll look impressive and more importantly it will bring a smile to your face. Try it next time you hit the dance floor or just in your kitchen but perhaps not in your local supermarket. It tickled me pink.
