Roark, I make those noises when eating something really delicious too.
Such as the time we (all girlfriends) were at the Greek Restaurant (BIG Greek population here, my best friends are all Greek)
and we had just sampled a little of everything on the menu for dinner, sharing several plates of different Greek foods.
We were stuffed, but we ordered dessert anyway...and I ordered Baklava.
I don't usually have sweets, but we were going out dancing afterwards, and I was gonna dance it off.
It was late, the restaurant was deserted except for our table, and I bit into my Baklava.
(everyone else was eating their own desserts, so it was quiet)
I was so thoroughly enjoying it that I didn't noticed anything else for the delicious moment, stopped for a sip of coffee to wash it down...
and heard a muffled giggle, felt a nudging kick under the table, and looked around to see who kicked me. My friend Lynn was silently in hysterics...
and pointed her chin at the table where the chef and kitchen help (all Greek men) were sitting having coffee,
waiting for us to leave, and watching, listening to me eat my Baklava.
They were all dropped jawed and staring, listening to my estatic yummy noises I was making while eating the Baklava.
So I held up a forkful of Baklava and said:
" Compliments To The Chef!" and within 10 seconds, I knew who the chef was by the color of his face.
