You were trying to get everyone's attention (everyone being Theo, Draco, Enzo, Mathheo and Tom), you wanted to show off that you learned how to pronounce a word in English. You were a slow learner, so it difficult to work with when it came to learning.

"Alright everybody.. SEX! Now that I have your attention-" You said, but Draco cut you off. "You don't have my attention." So you yelled; "MONEY!" Draco smiled. "Alright, I'm listening." Next, Mathheo spoke up. "You had me at sex."
