Coworker hasn’t spoken to me in days why?

The other day i walked in my office and started on my work since i was a little late. After finishing what i had to do i went to my coworkers desk to ask about his morning. He was upset and said “you don’t have to worry about me speaking to you ever again” then i said why” and he said “we need to talk” and i said “about what?”
Then he said “just stop talking to me you came in didn’t speak now you want to speak”

What did i do why is he mad?
