I'm not going to my coworkers birthday lunch
Why don't you want to go to their lunch?
I just do not feel like I have a good time with them. They are super annoying.
You should go to your coworker's birthday. They want you to be there, even if it's not productive.
It's not like I want to go. I'm doing this on purpose with a smile and a good friendship.
But don't you think your coworker would want you there for their birthday?
