Until I got older any new job always came with a new nickname and catching a lot of [bleep] from everyone. You roll with the punches unless it gets personal. Do your job and dont be a bitch and pretty soon you are part of the team. Sensitive types never last. We had one fella we named Illene because he was always leaning on something.
That's kind of how it was in the firehouse. All the new kids get called kid. We all took a certain amount of chit for our rookie mistakes but there was always some vet that took pity and would help you unfug yourself. Now some of these stupid rookies fresh out of the academy will roll their eyes when you give them some extra chore to do.
