Going totally against the grain, I can see the OP's point.
My dd is applying at present.
She's applied to universities that take her predicted grades. You can see on line what she is likely to be offered for her course.
She was pleased, but not surprised to get the offers she has. They were exactly what she expected to be offered.
And they're offers. They still have to achieve the grades-that would be when I would expect the excitement.
I suppose if it wasn't one she expected to get an offer from, or considerably lower than expected, then she might be excited enough to text me straight away, but I think she'd wait until that evening, even if she knew I was at home doing nothing.
If she phoned and asked for me out of a meeting, then I would be expecting it to be something I absolutely needed to know that second. Which would probably mean it was bad, as she does not catastrophise, probably really bad.
I've just asked dd if people get excited about offers in school when they come through.
She said for most people it's either an aspirational offer-in which case they then start worrying about whether they'll be getting the grades, or not, in which case it's fairly as expected. Except medicine which is much more unknown whether they'll get any offers, so any offers there are usually greeted with huge relief.
Dd knows that what she's doing is important to me. She doesn't need to speak to me immediately for her to know that.
