Who is this person?

[Day by Day]

Here's what I'm responding to the email on seeing the kids today:

Good morning H,
Yes, the kids will be available today for you to see them. Although D13 will probably be at the barn.
I will return around 8:45-9 so you can stay longer than 8 if you like.
Have a safe trip.

Good enough, right? No pursuing. Polite, not too much convo.
