my part-time job

My part-time job begun at 7p.m to 3a.m. It was very hard for me, but I could try keeping smile to our customer thanks to my fellows. I like them very much however some of them will retire our store because of their future. I am very sad.... I want to retire together them but I was said my boss" You cannot retire the store together them" . I can work there because my future does not decided yet...
