You had severe daddy issues. Your dad was an alcoholic and often abusive if he was angry. You were sometimes childish to your friends (Theodore, Mattheo, Pansy, Draco, Enzo, Astoria, Daphne, Tom, Blaise and regulus) but they were used to it of course.
Right now, yous are in the Great Hall since yous have a free period and are talking and you keep talking about the most random stuff at a really quick pace.
You: "My dad is always telling me that i saw wayyyy to many words. He thinks that i say around 9 thousand everyday and believes that i should go to something like 15." You said innocently, obviously acting childish without realising.
After you said that, your friends started to look at you in sympathy and Mattheo started to rub your back up and down comforting you.
