How will Alien: Earth compare to alien films?

I am a seventeen-year-old homeschooler and until this September I have not been in any environments with public-schoolers. I recently got a job at my local pool as a swim instructor/lifeguard and have been spending time with my new coworkers who seem very different from me. Most of them are my peers and I desperately want to fit in with them, but don't know where to start. I don't understand most of what my coworkers talk about, I only use a minimal amount of slang, I've never dated anyone, I don't swear, and altogether I feel weird, awkward, insecure, and irrelevant. If you are a public-schooled teen, please help me know how to become more attractive and relatable to my coworkers while still being myself.
