Have you always wanted to say ‘no’ instead of ‘yes’ and still not upset your parents? Today is the day! What if you have to use a code to talk or understand everything today? If you mean to say ‘Mum, please come to me!’ you actually say ‘Dad, go away!’

Go on a treasure hunt and solve the riddles that are encoded, too! Look around you and notice each opposite pair or phenomenon: mum is short, dad is tall; I like salty snacks, my brother likes sweets; my neighbours have got a cat, we have got a dog, etc.

Share your findings in a funny dialogue you act with someone from your family-group. Wear opposite colours all day. Play games with opposite words and encoded instructions! Be Upside Down!
