Similes

This week, we've been learning about "similes". Similes are where you describe
something with something else like "The water was as dark as space" With Mrs Higgins, we had to write a paragraph with three similes. This is mine:
As dark as a night sky

As the water lapped the edge of the glass, th e fish swam as quick as a cheetah. The water looked freezing. It was so murky. The rock looked so sharp, if you touched it would cut you in a flash. The whole scene looked as dark as a night sky.
