I think we've all come up with creative ways to not say something negative about someone else's kid:
"Shake it off"
"Nice try"
"Good effort"
"Dammit Eliose, at least try to get the ball"
"Get 'em next time"
"Not your pitch"
Which is what I mean to say. Unfortunately sometimes what comes out is something like “Are you f-Ing kidding me”. It’s not often but it’s happened before.
