That's the best way I've found to deal with it, too. Just go with the flow.
My son has a phone that alerts him whenever he gets an email in his personal or work mailbox. I sent him something one night around 2 AM and he called me to see if I was okay!

Scared the daylights out of me to have the phone ring at that hour

but after I restarted my heart I told him I wouldn't be sending him anymore late-night email.
