Sarcasm

After meeting Severus, Bellatrix decides there's something wrong with him for using so much sarcasm

Before I met Severus I never believed that someone could use sarcasm in nearly every sentence that they spoke but he proved me wrong. In that first hour that I met him Severus used sarcasm so often that it began to annoy me. It was then that I decided that I didn't like him. There must have been something seriously wrong with him if he had the need to always be sarcastic. My sister Narcissa quite liked him but he grated on my nerves. Sarcasm should not be used that much in normal conversation. Occasionally is fine but not every damn sentence!
