New Kid in Town Struggles to Blend In

Moving to a new city has been quite the adventure. I decided to join a local gym to meet people and get acclimated faster, but little did I know that my social skills are not as polished as I thought they were. The first day was brutal, I kept forgetting to introduce myself properly, ended up in the wrong classes, and somehow managed to spill water all over the locker room floor. Despite this, every time I try again, I still feel like an outsider. Am I the only one who struggles with these kinds of social mishaps when starting somewhere new? How do others cope? Is there a magic trick for fitting in quickly?
