The Rattle Snake

I`m gentle ,flexible but deadly, Patient when I`m sober, aggressive when I`m hungry, Humans!They think they are wise by setting 'trap', 'Trap' for me!but I can see it,for this I hiss....., many think I`m weak,but with my arrow teeth I go for the kill;and the venom flows through his blood stream and the heart stops making me to have a smooth feast. Slowly I move,twisting and rattling with my tail, You can touch me,sit on me,but my tail?... Please don`t go there,it`s the heart of my body, I`ll strike you dead if you do. I`m endowed celestially,when I fire my arrow teeth to any prey;it runs and staggered back to me for me to swallow; don`t underestimate me.
