Why do kid’s parents send them to school sick? Why do they lie about it?

I get it. Parents need to work. But it’s just so inconsiderate. <br><br>Today a child vomited at lunch. Their parents said it was just because of a virus they have and not Covid. They went home after that. <br><br>The kid who sat next to someone who tested positive for Covid 2 days ago? Oh, they stayed home today just to make sure. <br><br>Why can't kid tummy ache parents do that?
