Annoying coworker tried to talk to me this morning

I shut it down immediately. I wish she would take the hint- I DON'T LIKE YOU.

I used to chat with her, before I realized that the ONLY things she talks about are her home remodels, her preferences on everything, and basically anything else that centers around HERSELF. She never asks how YOU are, or what's new with your life. And she's the coworker who sings LOUDLY in the shared breakroom like everyone wants to hear her warbling. 😖 She also loudly talks to no one. Like, she'll walk in and narrate her every move to anyone in the room, such as "I guess I better get my morning coffee, I still have half an hour before I start my shift!" And everyone looks around like "Who tf is she talking to?"

I can't stand her!!!!
