I ETAd the original post with what my H says that expression means when he says it.

I realized that they are expressions that people use that I interpret as conversation stoppers...

Christian friends - "I'll pray for you"... that means really I'm done listening to you and I want you to go away...so just stop talking now and I'll put a word in with the big guy.. Once xT (Christian counseling) said that to me and I just stopped talking and then I started to get ready to leave like the session was over... and he said what's wrong ...times not up yet and I turned and looked at the clock behind my head and said Oh... I thought that was your way of saying stop talking.

Others - "I hear you...or I hear that"... means yep I understand what you saying but I have my own issues and they are just as big or bigger than yours so stop complaining and stop talking.
