I normally just chatter away out loud. I say thank you a lot too, out loud.

As a child, I was told to get on my knees, put my hands together in a little steeple gesture and always told to say the "now I lay me down to sleep" routine, and bless tons of people in my family. Haven't done that since (not like that).

Yes, normally just chatter unless it's something really really big/bad, I sometimes fall to my knees and ask for help.
