Creepy Vocabulary: Snag

Snag is a small problem or disadvantage.

E.g. Vera is a very intelligent girl. She spends a lot of her free time reading scientific sites. She has a powerful computer and fast broadband connection. But there is only one snag: she has no eyes and hands from now on. Her boyfriend got jealous, chopped off her hands and took out both her eyes out of her head using his grandfather's axe and pincers. Not funny, true. But at least she is alive and she can listen to the radio.

  Question:  Do you ever get jealous and have the urge to hurt someone? If not, why? If yes, why, why, why, whyyyyy ......?
