If you sent an email that said something like the following, would you expect some sort of response of at least "thanks"? Particularly if the other person pretty much always replies to your emails with something? Or does it seem more like, I don't know, a "thinking of you" card to which you wouldn't respond?

"Only sending this as an email because I didn't want to put you on the spot in session. But you seemed sad in session yesterday, and I just wanted to say that I hope you and your loved ones are OK (not prying). Or perhaps it was related to something in the news.* I'm not looking for an explanation, just wanted to share that. I hope this didn't feel intrusive, and if it did, I'm sorry."

He had also switched to virtual at the last minute, didn't say why except not Covid-related (I know, he doesn't owe me an explanation), and was wiping tears a couple random times during session. Yes, I know, I should leave the man alone. I'm not going to ask any questions about it in session today. But I'm going to feel terribly awkward if he doesn't acknowledge my email at all, either via email or during session. I sent it fairly early yesterday morning, so I'm sure he saw it.

Background that we're in the midst of conflict/rupture repair (that was mainly about my confirming sessions were in person, not virtual, and concerns about last-minute changes, so Wednesday also triggered me a bit), so I'm particularly sensitive to these things. I'm fully aware that I should not have sent the email, so it won't be helpful to tell me that. It's more like, is it cause for concern if he didn't reply with anything? I don't want to be needlessly anxious walking into session.

*I referenced the specific thing.
