Like offering help and shit?
Yeah, be useful.
I’m already useful at work. I do things. Complete tasks, smile at people, assist, assist,assist, so much that my elbows hurt.
Elbows, that’s the least of it.
Well, no. When elbows hurt that’s the most of it. And I am being so useful (You aren’t).  Seems to me your spending way too much time tellng me to be useful.
Shut up.
You shut up.
Be useful!
That is my useful, “Shut up!”
