I was always that kid, right up until around the time I graduated high school that was always asked, at least once a day, "What's wrong?" In fact, my friends liked to say I had a perpetual blah or evil expression, and others found me unapproachable because I had "resting bitch-face". My mom always complained that I didn't smile enough--which I thought was ridiculous; why should I walk around smiling if I had nothing particular to smile about? This changed though, probably when I started dating my now husband, who for some reason brought out a cutesey side of me. Coupled with my job in retail (where you're forced to smile and put on a lovely performance for your customers), and my then obsession with Anime, I grew expressive. Very expressive. People now say I'm very animated and cartoon-like with my facial expressions, tone of voice, and gestures/body movements. I still flat-line around my family & childhood friends, but everyone else seems to think I'm a very expressive person. I've always reasoned I became like this because I have a hard time getting people to understand me, so I exaggerate my expressions for it to be more obvious. But now I think maybe this is due to my possible autism. My facial expression can be so exaggerated now that some times its misleading or just portraying the wrong thought/emotion. My husband misunderstands me all the time. Also, I too have a tendency of copying other's (like actors, or cartoon characters) facial expressions and sayings, when its something I like.
