Yes I know she's busy but this is about something that's important to me as a parent. It's only been three days so far but I've not had a reply. Maybe the email went astray but it's unlikely.
I raised an issue a couple of months ago that was quite serious and didn't get a reply then either. Eventually it resolved itself but still. And with that one I know she definitely was handed a printed copy of the email.
I could go in for a meeting but the current issue does not really merit that - it's something she should be able to answer relatively quickly and I don't want to take up an appointment. Plus last time I tried to arrange a meeting there wasn't a slot free for weeks.
She has a reputation for hiding from parents. I suppose this should be in AIBU...to expect a reply?
