Chipunk Face

Growing up, I always thought I was alone with this problem. The only person I'll eat around is my brother- he's 8 and he's too busy shoving food in his mouth and on his shirt to pay attention lol.
I never grew up in eating. Like, I still push food around the plate to make smiley faces. I pick at food but don't eat it. I play with finger foods like grapes and use them as eyeballs in my smiley faces. And I always have chipmunk cheeks when I eat and I absolutely can't stand it. Not to mention people who converse while eating! How do people do it? I can't eat in front of anyone but my brother xD
