Annoying colleague, annoying model


I am at an event for a week with a colleague. Here is my model:
C: He’s younger, less experienced. We are working together for a week abroad.
T: He’s annoying. He’s childish. He’s so slow. He’s unprofessional.
F: Annoyed
A: Be hypercritical, look at every single mistake he makes, don’t appreciate him, his presence and his work.
R: I am not professional.

I want to feel compassion and show up as an example for both of us. I am annoyed at being annoyed! I am struggling with the right direction to take.
Thanks for your help!
