What shocked you back to reality was not the laughter, it was your fighting the laughter. It was that little voice in the back of your head that was saying, "HE is going to think you are laughing at HIM! You are going to be in such trouble."
It took Dragon a very long time to teach me that whatever reactions i had were ok. If i laugh, cry, hiccup, fart or howl like a lunatic (yes i have on a few occasions), He accepts it and goes with the flow. It took a long time for me to trust him to do that, to trust him with whatever honest reaction took me.
EEK! rambling again.
