On a few occasions. Usually it is a sense of being overwhelmed with love for Him and by the beauty of us being together. There just aren't words sometimes for the intense emotions that happen, and then yes... the only logical response is to cry. LOL Or cry and laugh... or whatever.

The only other time I've cried that wasn't quite like this was during sub-drop, but I assumed you were talking about being in a fairly rational state of mind when you started crying, so this has less to do with that.
