You need me, though you fear me.
I start life small, but with each meal I become more fearsome.
I never bathe for fear of dying.
My smell overcomes passersby, choking the life from them.
The enemy of water is my friend;
I’ll admit our friendship can get quite heated.
I could be your warmest companion.
I could bring bright light to your life.
Spurn me and I could burn you or leave you cold.
