Posting a critical comment about a private correspondence isn't likely to woo him back or make him feel welcome. It seems more like "public chastisement" that I'm sure no one on this forum would appreciate receiving from you.
There was no private correspondence, just my e-mail to him which went without response. That is not chastisement - I"m posting the fact that it irked me, just as I would post about anything that irks me, as you well know. You can speak for yourself, of course, but not for others on this board. I did find his behavior odd - I said it here. That's not chastisement, just my opinion, as you well know. I sent him a nice e-mail stating the facts as I saw them, and I have stated those same facts here since I found out about it. If someone needs a long break, then so be it. If someone comes back and cuts the break short, great. I see no need to woo or not woo - I haven't seen much evidence of people holding back their opinions and I'm certainly not holding back mine. What people "appreciate" or not appreciate is, I'm sure you'll agree, their business and I'm equally sure you don't need to speak for them, as they all stand up and make themselves heard perfectly well.
This is not a public chastisement, unless one were to consider your post a public chastisement.
