I don’t know how vague you need it so i’ll give you options to choose from hahah:
some girl’s mom bought her toothpaste at the grocery store
her mom bought her toothpaste at the grocery store.
a parent bought their child toothpaste at the grocery store.
someone’s parent bought them toothpaste at the grocery store
their mom bought them toothpaste at the grocery store.
if you need something different, i’ll be more than happy to come up with more but i hope this helped:)
I believe that the phrase from Mandela's speech that is an example of a metaphor is the first one - 'the children, [...] the greatest of our treasures."
A metaphor is a type of comparison, where two or more things are compared without using words such as <em>like </em>or <em>as. </em>Here, the children are the greatest of our treasures - they are compared to a treasure, something which is the most important thing of all.
