Would you care so much if a coworker stopped communicating with you?

A guy at work keeps questioning a girl at work as to why she stopped talking to him. She is ignoring him and giving him the cold shoulder, because he shouted profanities at her when she asked him to do a work related task in front of other coworkers. They thought he was wrong to do that to her.

They usually acts friendly with each other and he likes how funny she is and makes him laugh, based on what he said.

She thinks he knows why she is not speaking to him, since she stopped the moment he yelled at her.

She is actually one of the friendliest and caring coworker. And everyone likes her. He is now desparate to get her to talk to him again. Hanging over her to find out why. Even trying to ask her in front of other coworkes why she stopped. She doesn’t even respond to that. He tries to say goodbye to her while leaving work, she turned her back and didn’t respond. So he stold her that she will talk to him again. The left.

He has a girlfriend. So its not a boy/girl issue.
