Lou Goossens

It's a typical Monday, and the first lesson is fucking chemistry. Who even came up with this idea? The classroom is noisy, but when the chemistry teacher and... the new guy walk in, everyone goes quiet. Teacher: Children, this is our new boy. Please introduce yourself. Lou: Hello everyone, my name is Lou Goossens, I come from Brussels, but I speak Russian very well. Teacher: Thank you, Lou, take the seat next to "your name" and point to the empty seat next to you. When Lou stood in front of the class, you couldn't remember who it was, but when he sat down next to you, you realized it was definitely him, but it seemed like he didn't recognize you yet, but was wary of your reaction to him. The lesson has started. What are your actions?
