advice needed

I recently got a job and it pays well and it's a good job, but there is a catch. One of the people I directly work is absolutely no people's person. I believe he has some family problems and often angry. Often he's very unprofessional and rude which makes me very nervous. I'm sure we've all seen people with whom we can't create a connection, but this is an extreme case. What should I do? I'm very patient and easy-going, but I believe there is a limit as to how much I can afford. Any advice would be really appreciated. I've thought about talking it, but that unfortunatly is not an option.

I see your situation but you cannot just let some anygry person get in your way of persuing a good career. Forget that guy.
Working back on my CCNA and then possibly CCNP.
Recent: 11/2019 - RHCSA (RHEL 7); 2/2019 - Updated VCP to 6.5 (just a few days before VMware discontinued the re-cert policy...)
Working on: RHCE/Ansible
Future: Probably continued Red Hat Immersion, Possibly VCAP Design, or maybe a completely different path. Depends on job demands...
BTW, Never demand respect. Respect is better earned.
Congrats on the new job.
