I guess it's excitement? I could never really jump around feeling excited. All I always do is smile. There were times when people asked me, "Aren't you excited? You don't look like you are." Honestly, I am genuinely excited. It's just that I couldn't express it well.

I don't really know the reason behind it, but I guess I don't find it necessary to shout, jump around, or flail when I'm excited.
