That's okay, I'm really a nice person and I don't show it a lot...That's actually a lie, but thought I'd give it a go... Just as long as you are happy, it doesn't really matter if you show it or not...
I'm the same way. I'm always pretty happy, or atleast content, but everyone thinks I either look sad or pissed off most of the time. I guess I'm kind of decieving.
