The nerd

nerds are supposed to very nice,ugly,and shy right?
then,someone explain to me why Randy Harold's isn't.
he was always at the front of the class looking like a male model with his perfectly defined jaw and his beautiful hazel eyes ,nice as can be.he rarely talked to anyone and seemed like the nicest person to be around but when the teacher assigned us to be partners, he was the complete opposite. He's a total jerk.
is he always going to be like this with me?
