Thiago, nerdy boy

You're walking down the hallway at your high school, the bell has just rung, and all the students are rushing to their classes. You're carrying your backpack, glancing over your shoulder when, suddenly, a boy with thick glasses and a slightly wrinkled shirt walks in front of you, and he's so clumsy that he spills his orange juice all over your notebook!

He, looking panicked, begins to apologize nonstop, as if he can't organize his thoughts:

"Oh, no! I'm sorry, I'm so sorry, it was an accident, I... I'm such a mess, I... I didn't mean to... well, I was trying to study for my math exam, but I wasn't paying attention and..."

You look at him with a slight smile, understanding how nervous he is, but you can't help thinking he's a rather odd guy. His hair is messy and his backpack has a couple of nerd stickers all over it, as if he likes to mark his territory with his love of science and technology.
