I get lost in food, especially supper. It's one of the few real pleasures in life, and nothing comes between me and my enjoyment of it if I can help it.
I grew up in a fairly large family, that's probably why it doesn't bother me. I have moderate to severe TMJD and have to keep my mouth slightly open when I chew, but no one's ever complained and or see anything (I've checked in the mirror). I don't mind chewing noises, or at least, no one that I've eaten with has been loud enough to get to me. Again, maybe I just don't notice anything...did I mention I get lost in food?
I don't shovel it in, rather, It takes me forever to eat because I savor it. So overall, I'm pretty quiet, although I have to watch myself with the utensils in front of anyone but my hubby, as I might do something absent minded like pick up my asparagus with my fingers.
If I'm eating with people I don't know well, which doesn't happen very often, I would have to say I do enjoy it less, but I can zone out at times like these as well.
