People... A phobia is when you have an irrational fear of something... Not simply a fear.
E.g. of a fear of snakes: Johnny saw a snake in the classroom, afraid, he moved towards the door and left the classroom.
E.g of Ophidiophobia: Johnny saw a picture of a sausage and assumed it was a snake, Johnny proceeded to claw his way through all his peers before proceeding to kick down the wall and leave the classroom.
