Coming from someone that has been in for 3 years. It’s going to happen all the time. You aren’t around people from the same town as you anymore. Instead it’s people from all over the world, with different goals, attitudes, etc. I currently work with an individual that seems to have it out for me and in some way always makes the comment that “oh he’s going to be an officer” or things along that nature. It’s obviously negative and comes off slightly jealous at times. If you easily get offended or your feelings get hurt, take this time to work on that because it’s just how it goes.
