I am afraid of snakes.  I almost stepped on one when i was a child and i have had a phobia about them ever since.
I'm not afraid of them but understand. After that rapid onset of fear phobias can last a long time
About 2 years ago i was sitting under my brother's deck and a poisonous snake drooped down almost on me.  A very frightening experience!
Oh wow, that would be frightening! Do you know what type of snake it was? 
No, but it was a pit viper, with the distinctive wedge shaped head.  I caught it.
You caught it?! You are so brave. Snakebites can be very serious
Then one day i saw a racer snake.  I would see it coil up and fly through the air when it saw prey.  It was 7 or 8 feet long, but harmless. It still scared me because it was so fast.
Fly through the air! That is wild! That would be very cool to see though.
Then i caught one in my bedroom, just a baby, 2 feet long or so.  That house was snake infested. I am glad i moved.
