The word for the week is impossibility. My original idea was to do life on other planets, but due to a faulty scanner I chose to do this one instead. This shows impossibility because although cows can climb up stairs, they can not come down.
The word for I Friday was fleeting. I did not know what this word meant at all so I looked it up on dictionary.com which said that fleeting is vanishing quickly. In my illustration, I showed birds leaving the nest as fleeting because although their parents look after them for so long, once they are ready they vanish quickly in the distance.
