You are curently on a big boat. You are a sailor and you and your collegues were sent to Argentina to deliver fruits and vegetables. As you are standing and skillfully pretending to do your job, you don´t have to actually do anything. Sudenly one of your fellow collegues come to you biting his nails and looking nervous.

Ask him if he´s okay
Simply ignore him. (I mean...this guy is always nervous, why would you bother him and yourself by asking stupid questions.)
