My coworker came out of the bathroom with toilet paper stuck to his shoe. Funny enough, I didn't tell him.
Why? Do you want him embarrassed?
He's really obnoxious, so I avoid talking to him in general.
So you'd rather watch him get embarrassed than inform him of the toilet paper?
Yeah, and I'll probably make fun of him, too.
This seems like inappropriate work behavior on your part. I'm sure you'd want someone to tell you about toilet paper on your shoe.
