5 original similes

My 5 original similes
As sharp as a corner of a bench top in a daycare.
As shiny as a thin slice of metal when it touches the light.
As relaxed as my Nan when she sunbathes in the dunes of Hawaii.
Intricate like an immune system, every part playing an important role.
Burning like the fury in my Dad's eyes when I forget to do the chores.
