Dr. Pepper, you are the kindest, most gentle, sensitive and thoughtful poster on this forum. By a wide margin. That’s without even speaking of your superior intelligence. (No offense intended towards squeak.) I’m very confident that telling a poster that he’s bitter (or worse) isn’t something you’ve previously directly said to anyone here. And doubtlessly you’ve had ample opportunities in the well over a decade you’ve graced us with your special presence.
If I’m wrong about the above I’ll eat my words. But I know that I am not.
All that said, addressing a person’s bitterness isn’t necessarily a negative. Indeed it can be helpful in assisting your interlocutor address that very issue that you’ve identified to him. Also note that while it was strong and sharp comparative to your previous comments, in the grand scheme of conversations it certainly was far from being a harsh comment. I merely noticed that it was outside the typical tone of a comment coming from yourself.
Ah Gut Shabbos and ah Gutten Chodesh!
