Our county fair is next week, the kids have projects, the entire town goes. Just wanted to be able to have a simple comment without going into detail.
Well, if my kids had projects at the county fair (how exciting is that? animals?), i would be coldly furious if anyone had the nerve to bring that foolishness to me in front of my kids.
You could say,
"Today is about my children, they have worked hard on their projects. We are past that now."
and turn away.
