Am I taking it the wrong way or should I say something

[daycarediva]

I would have immediately said, "I'm sorry, maybe you didn't hear me. ARE THE KIDS GOING TO BE PICKED UP EARLY TODAY? "

It'd be really hard to ignore me and I won't be ignored by a child OR an adult. Ever.

I would do this, too. After he answered me, because I would seriously repeat myself until he did. I would ask him point blank if he had any issues he would like to discuss. If he said no, then I would say "GREAT!" and if he wanted to talk about the late fee issue, then I would talk about it, but I would make it clear that he needs to be able to communicate with me.
