Came back from getting my masters degree and I had an issue with my coworker and my boss said

Ahhh if only I didn’t need a new part for my car:/// . Basically I’ve work at this place since it opened last year, quit on very good terms, boss asked me to come back. Has an issue w a new coworker but all was resolved and same boss said this. I’m just a part time employee in a tourism area but it still sucks haha
