Just curious what is taking so long to talk about? My parents (who ask) usually just say "good day?" I say yep or if not I will say - we didn't bring our listening ears today, we had a timeout because we were pushing our friends today or we had a potty accident etc. I don't go into full on detail about the whole incident because I have already dealt with it and disciplined accordingly.
In the event something major needs to be addressed I send an email to parent during the day.
